What to do When OneDrive is Full

Is your computer telling you that your OneDrive is full? It’s one of the most common problems Windows users run into, and the strange part is that most people have never knowingly uploaded a single file to it.

OneDrive is a sync tool, not a backup tool, whatever Microsoft call it. You get 5 GB of free storage and it fills up far quicker than you’d expect. Once it’s full, things start breaking, and some of them aren’t obvious at all. Your emails are the big one.

In this guide I’ll show you what a full OneDrive actually does to your PC, why it filled up in the first place, and exactly what to do about it. Most importantly, I’ll show you how to do it without losing any files, because that’s where people come unstuck.

Does It Matter if OneDrive Is Full

The short answer is yes, and it matters a lot more than most people realise.

Microsoft has tied OneDrive into the rest of your Microsoft account, so a full OneDrive doesn’t simply stop you saving files to the cloud. It sets off a chain of problems, and one of them will stop your email dead.

What Stops Working Straight Away

The moment you go over your storage limit, all of this happens at once.

• Your email stops. You can’t send or receive anything on an Outlook.com, Hotmail or Live address. Microsoft are quite clear about this, it happens even if your mailbox itself is nowhere near full. It catches people out constantly, because nothing about the error message mentions OneDrive. I’ve written that one up separately, Microsoft Email Accounts Not Sending Or Receiving Emails.
• Syncing stops. Any change you make to a file on your PC won’t reach the cloud. Your online copies quietly go stale.
• Your files go read only. You can open them and look at them, but you can’t save changes back. In Microsoft Office you’ll see the message “This document is stored in a location that’s full”, which is Office’s way of telling you the same thing.
• Teams attachments stop. If you use Teams, you can’t send or receive messages with files attached.

What Happens if You Leave It

This is the part almost nobody knows about, and it’s the reason I say don’t just ignore a full OneDrive.

Microsoft run a timetable on accounts that stay over the limit.

• Over your limit for 3 months, your OneDrive account is frozen. Frozen means everything above stays broken and you can’t do anything with the account until you get back under your quota.
• After 6 months, in Microsoft’s own words, they may delete your OneDrive and all the files in it, and once deleted those files are not recoverable.

That’s the worst case, and it takes half a year to get there. But since OneDrive works by syncing, files that only ever lived in the cloud would go with it. That’s why the first proper job in this guide is making sure everything is safely on your computer before you touch anything.

Why Is My OneDrive Full

Almost always, it’s because OneDrive was switched on and then quietly did exactly what it was designed to do.

Once it’s enabled, OneDrive takes everything in your Desktop, Documents and Pictures folders and moves it online into your OneDrive storage. Not copies, it moves them. Years of photos and documents go up into a 5 GB space, and that’s why it’s full.

You probably switched it on without realising. Microsoft push OneDrive hard as a backup solution, and the splash screen below appears during setup, and then pops up again at random when you start your PC. It asks if you’d like to protect your files and memories. Who says no to that?

What Counts Towards Your 5 GB

More things than you’d think, and this is where the email problem comes from. A free Microsoft account gives you two separate allowances.

• 15 GB of mailbox storage for your Outlook.com emails, contacts and calendar.
• 5 GB of cloud storage, shared between your OneDrive files, your photos and your email attachments.

So every large attachment anyone has ever emailed you is eating into the same 5 GB as your photos. And anything sitting in your OneDrive recycle bin is still counted too, which surprises a lot of people. More on that in a moment.

My OneDrive Says It’s Full When It’s Not

This one comes up a lot. You look at your OneDrive, there’s hardly anything in it, and Microsoft still insist you’re out of space. You’re not going mad, there are four common reasons for it.

Sign in to OneDrive then click the Settings icon (gear wheel) in the top right corner. On the menu, click Manage.

The Manage Storage page opens. This shows you where your space is being used up. There are two possibilities, it’s either going to be the files stored on OneDrive or possibly it could be your emails.

Beside “Free up Space”, click OneDrive.

Now you can see all your files and folders stored in OneDrive. Not only that but you can also see the actual size of each item. That allows you to find the biggest space hogs and decide what to do about them.
The other useful link on this page is the OneDrive Recycle Bin.

Your Deleted Files Are Still in the Recycle Bin

This is the number one cause, and it’s the reason people delete half their files and see no change at all.

OneDrive has its own recycle bin online, completely separate from the recycle bin on your PC. Anything you delete goes in there and stays for 30 days, and the whole time it’s still using up your storage. Deleting files without emptying that bin frees up precisely nothing.

To empty it, go to onedrive.com, sign in, and click Recycle bin in the panel on the left. Check what’s in there first, then click Empty recycle bin.

A Folder Somebody Shared With You

If someone has shared a large folder with you and you added it to your own OneDrive, it can push your account over the limit. It isn’t your folder and you didn’t upload it, but it counts against you.

Have a look in the Shared section on onedrive.com. If there’s something big in there that you don’t need, remove it from your OneDrive. It stays in the other person’s account, you’re only removing your link to it.

A Subscription That Quietly Ran Out

If you had a Microsoft 365 subscription that expired or a payment that failed, your storage drops back to 5 GB. Nothing gets deleted, but if you were using 200 GB you are now very definitely over the limit.

The same thing happens with the bonus storage that gets bundled with some phones and laptops. Those Samsung and manufacturer offers of 100 GB free are temporary, and when they lapse the space goes with them.

Give It a Couple of Hours

Microsoft don’t update your storage figure instantly. After you’ve deleted things and emptied the recycle bin, it can take up to 2 hours for your account to catch up and start working normally again.

So make a cup of tea rather than deleting more files in frustration. Microsoft’s own advice is that if you’re still stuck 4 hours later, that’s the point to contact their support.

Before You Delete Anything

Read this bit before you start clearing space. It’s the most important section on the page.

You can’t just start deleting files and folders from OneDrive, because it’s a sync tool. Whatever you delete online is deleted from your computer as well. That’s the trap, and it’s how people lose things.

So first, find out what’s actually on your PC and what only exists in the cloud. Open File Explorer and look at the little symbol beside each file and folder. You might be surprised how much of your stuff isn’t on your computer at all.

Download Everything to Your Computer

To make sure you can’t lose anything, bring it all down onto your PC first. The easiest way is to change the status of each synced folder.

1. Right click on the folder, then left click “Always keep on this device”. Do that to each synced folder, including the one with the red circle and white cross beside it.
2. Click the OneDrive cloud icon on your taskbar to watch the progress. It can take a while if there’s a lot to bring down.
3. When it’s finished, open File Explorer and check your folders now show the green circle with the white tick.
4. Open each folder and check that every subfolder and file inside is on your computer too.

This doesn’t move your files out of OneDrive. It tells OneDrive to keep copies both online and on your computer, which is exactly what you want before you start deleting.

One folder will probably stay marked with a red circle and white cross. That’s the folder that’s too big for the space you’ve got left, and it’s the one causing all the trouble.

What to Do When OneDrive Is Full

Now that everything is safely on your computer, you can decide what you actually want to do. You’ve got three sensible options, and they range from a small adjustment to switching OneDrive off completely.

• Stop syncing the folder that’s too big. Usually it’s one of the three, Desktop, Documents or Pictures. Deselect that one and carry on using OneDrive for the others.
• Move the offending file or folder somewhere else. Sometimes it’s a single big folder of photos or videos. Cut and paste it to another location on your PC and the problem goes away.
• Stop using OneDrive altogether by unlinking your PC from it. Nothing syncs any more and your files stay on your computer.

Whichever you pick, you’ll still need to clear out what’s already sitting in your OneDrive storage. I’ll come to that after these three.

How to Deselect a Folder from OneDrive

Often it’s just one of your three folders that’s too big for the space you have. Deselect that one and OneDrive carries on syncing the others quite happily.

1. Right click the OneDrive cloud icon on your taskbar, then left click Settings. You might need to click the gear wheel icon first.
2. On the Sync and backup page, click Manage backup.
3. Click the toggle switch beside the folder you want to stop syncing.

Stop Backing Up to OneDrive

When you flip that toggle off, OneDrive asks where you want to keep the files. This next bit matters, so read the options rather than clicking through them.

1. Select “Stop backup and choose where to keep files”, then select “Only on my PC”.
2. Click OK on the confirmation popup.
3. Open File Explorer and check that the folder you deselected has stopped syncing.

How to Disable OneDrive on Your PC

If you’ve had enough of it, the cleanest way to disable OneDrive is to unlink it from your PC. Your files stay exactly where they are on your computer, OneDrive simply stops syncing them.

1. Right click the OneDrive cloud icon on your taskbar, then left click Settings. Again, you might need the gear wheel first.
2. On the Sync and backup page, click Account in the left hand panel.
3. Click Unlink this PC.
4. Click Unlink account on the confirmation popup.

How to Free Up Space in OneDrive

With your files safely on your computer, you can clear out the online copies. Do this in a web browser rather than in File Explorer, so there’s no chance of the sync tool doing something you didn’t expect.

1. Go to onedrive.com and sign in with your Microsoft account.
2. Click My files, select what you want to remove, then click Delete.
3. Click Recycle bin, check what’s in there, then click Empty recycle bin.

That third step is the one everybody skips, and it’s the one that actually gives you the space back. Deleted files sit in the OneDrive recycle bin for 30 days and count against your storage the whole time.

Remember that anything you delete here also disappears from your PC, which is exactly why we downloaded everything first. There’s a lot more to say about deleting safely, including how to remove files from OneDrive while keeping them on your computer, so I’ve given it a guide of its own. How to Delete Files from OneDrive.

How to Clear OneDrive Storage Without Deleting Files

There’s one thing I need to warn you about here, because it trips up nearly everybody.

Right click any file in your OneDrive folder and you’ll see an option called “Free up space”. It sounds exactly like what you need. It isn’t.

Free up space clears room on your hard drive, not in your OneDrive. It takes the local copy off your computer and leaves the file online, turning it into a blue cloud file. Your OneDrive storage doesn’t change by a single byte. If your OneDrive is full and you click it, nothing you care about will get better, and you’ll have made your files harder to reach when you’re offline.

So if you want to clear your OneDrive storage without losing files, the answer is to move them, not delete them. You have a few ways to do that.

• Move files out of OneDrive into an ordinary folder on your PC. Make a new folder somewhere outside OneDrive, on your C drive is fine, then cut and paste the files into it. They leave OneDrive, they stay on your computer.
• Copy them onto a USB drive or external hard drive. Photos and videos are usually the bulk of the problem, and they’re happier on a drive of their own anyway. Here’s how to copy files to a USB drive.
• Stop syncing the folder, as covered further up. The files stay on your PC and OneDrive lets go of them.
• Empty the OneDrive recycle bin. Costs you nothing if the files in it are already gone from your PC as well.

If you want a proper backup rather than a sync, and this is worth thinking about, have a look at how to set up FreeFileSync. It’s free, it copies to a USB drive or another PC on your network, and nothing you delete in one place vanishes from the other.

Why Your Emails Have Stopped

If you landed here because your email stopped working, this is the bit you need.

Microsoft treat your OneDrive storage and your email as one account. When the cloud storage is full, Outlook.com, Hotmail and Live addresses stop sending and receiving, and it makes no difference how much room is left in the mailbox itself. That’s why people spend an afternoon deleting old emails and nothing improves.

Free up space in OneDrive using the steps above, empty the recycle bin, then give it up to two hours. Your email should start flowing again on its own.

There’s more to it than that if attachments are your real problem, and I’ve covered the whole thing here, Outlook.com Not Sending or Receiving Emails.

Getting More OneDrive Storage

Sometimes the honest answer is that 5 GB isn’t enough for you, and no amount of tidying will change that. Buying more storage is a perfectly reasonable fix, and it’s cheaper than most people expect.

These are the UK prices as I write this in September 2026.

• Free, 5 GB of cloud storage plus a 15 GB mailbox.
• Microsoft 365 Basic, £1.99 a month or £19.99 a year. 100 GB of cloud storage and a 100 GB mailbox.
• Microsoft 365 Personal, £8.49 a month or £84.99 a year. 1 TB of storage, and the Office apps.
• Microsoft 365 Family, £10.49 a month or £104.99 a year. 1 TB each for up to six people.

For nearly everyone reading this page, Basic is the one. Two pounds a month turns 5 GB into 100 GB, which is twenty times the space, and it lifts your mailbox to 100 GB at the same time. If the email problem is what brought you here, that single change fixes both halves of it.

Personal and Family only make sense if you actually want the Office apps. Don’t pay £85 a year for storage you could have for £20.

And it’s worth saying plainly, paying Microsoft isn’t your only option. A 128 GB USB stick costs about a tenner once and doesn’t renew every year. Cloud storage is convenient, it isn’t compulsory.

Troubleshooting

I Deleted Files but OneDrive Still Says It’s Full

Nine times out of ten it’s the recycle bin. Go to onedrive.com, click Recycle bin, and empty it. Then wait, because Microsoft can take up to two hours to update your storage figure.

If it’s been more than four hours and nothing has changed, that’s when it’s worth contacting Microsoft support rather than deleting anything else.

Everything Is Read Only and I Can’t Save Anything

That’s the expected behaviour when you’re over your limit, and it’s not a fault with your PC. You can still open and read your files, and you can still delete things to get back under the limit. Once you’re under, the read only lock lifts by itself.

If you have work you can’t afford to lose in an open document, use File then Save As and save it somewhere outside OneDrive first. Your Desktop will do if it isn’t synced. Have a look at the difference between Save and Save As if that isn’t something you’ve used before.

A Folder Shows a Red Circle with a White Cross

That’s OneDrive telling you it can’t sync that folder, and when your storage is full it’s because the folder won’t fit in the space you have left. It’s a useful marker rather than a problem in itself. That folder is the one to deselect or move.

I Deleted Files Online and They Vanished from My PC

This is the sync trap, and it’s recoverable if you act quickly. Go to onedrive.com, open the Recycle bin, select the files and click Restore. You have 30 days before they’re gone for good.

It’s also the reason the “Before you delete anything” section sits where it does on this page.

Office Says “This Document Is Stored in a Location That’s Full”

Word, Excel and PowerPoint show this when you try to save into a OneDrive that has no room left. It’s the same problem wearing a different message.

To rescue what’s on screen right now, use Save As and pick a folder outside OneDrive. Then come back and clear the space properly.

Frequently Asked Questions

Q. Does it matter if my OneDrive is full?
A. Yes. Straight away you can’t send or receive Outlook.com email, your files become read only and syncing stops. If you stay over the limit for three months Microsoft freeze the account, and after six months they may delete everything in it.

Q. Why does my OneDrive say it’s full when it’s empty?
A. Almost always the OneDrive recycle bin. Deleted files stay there for 30 days and keep using your storage until you empty it. Other causes are a large folder somebody shared with you, or a subscription that expired and dropped you back to 5 GB.

Q. Will I lose my files if I turn OneDrive off?
A. No, as long as you download everything to your PC first. Unlinking your computer from OneDrive leaves your files where they are, it just stops them syncing.

Q. Does “Free up space” free up my OneDrive storage?
A. No. It frees space on your hard drive by removing the local copy and leaving the file online. Your OneDrive storage stays exactly the same.

Q. Why can’t I send emails when it’s my OneDrive that’s full?
A. Microsoft share one storage allowance across OneDrive files, photos and email attachments. Go over it and Outlook.com stops working, even if your mailbox is nearly empty.

Q. How long does it take to work again after I delete files?
A. Up to two hours. If you’re still stuck after four, contact Microsoft support.

Q. How much does more OneDrive storage cost?
A. Microsoft 365 Basic is £1.99 a month or £19.99 a year and gives you 100 GB of storage plus a 100 GB mailbox. That’s the sensible choice for most home users.

Q. Can I use OneDrive without it syncing my Desktop and Documents?
A. Yes. Open OneDrive settings, go to Sync and backup, then Manage backup, and switch off the folders you don’t want synced. OneDrive carries on working for everything else.

Summary

A full OneDrive causes far more trouble than it looks like it should. Your email stops, your files go read only, and if you leave it long enough Microsoft will freeze the account and eventually delete what’s in it.

The order matters more than anything else. Get your files onto your computer first, then clear the space, then empty the recycle bin. Do it in that order and you can’t lose anything. Do it the other way round and you might.

Personally, I unlink OneDrive. It’s far too easy to delete something in one place and find it gone from the other. But if you want to keep using it sensibly, and there’s a good case for that, read How to Setup OneDrive to Backup Your Files and set it up so this doesn’t happen again.
