OneDrive & Microsoft storage
OneDrive is full — and now your email is bouncing
Take a breath: your files are NOT deleted, and your email account is not gone. A full OneDrive and broken Outlook.com email are the same problem wearing two hats — Microsoft just never explains the connection on one page. Below is the plain-English version: why it happens, the real deadlines, and the fastest way back under the limit. If you’d rather not touch it, we’ll sort it remotely from £20 while you watch.

The collision
Why a full OneDrive stops your email working
Here’s the bit Microsoft splits across four different help pages. A free Microsoft account comes with 5GB of cloud storage, and that pool is shared between your OneDrive files and the attachments sitting in your Outlook.com email. Your mailbox itself has a separate 15GB allowance — but the 5GB pool is the one that fills up first, usually with phone photos you didn’t know were backing up.
And Microsoft’s own rules are blunt: once your account is over its storage quota, you can’t send or receive email through Outlook.com — even if your mailbox is nowhere near its own 15GB limit. New messages sent to you are returned to the sender, which is why people started telling you your email “doesn’t work” before you noticed anything was wrong.
So the cure for your email problem lives in OneDrive, not in Outlook. (If your email is broken for a different reason — passwords, settings, the new Outlook app — see our guide to common Outlook problems instead.)
The countdown
What actually happens when OneDrive fills up
There is a timeline here, and knowing it stops the panic. None of it is instant, and nothing has been deleted yet.
- The moment you go over: new uploads stop, phone photo backup stops, files stop syncing — and Outlook.com email starts bouncing.
- Around three months over the limit: Microsoft can freeze the account. Frozen means your existing files go read-only — you can still open and download everything, but you can’t upload, edit or sync, and you can’t send Teams messages with attachments.
- Around six months frozen: Microsoft says it may delete your OneDrive and everything in it — and once that happens, the files are non-recoverable. “May” is Microsoft’s word, not a guarantee of a stay of execution. Don’t gamble on it.
Two reassurances worth repeating. First, frozen is not deleted — a frozen account with “empty-looking” folders on your PC is usually just sync being blocked, not lost data (if things genuinely look missing, start with files missing from OneDrive). Second, you can unfreeze it yourself today — the steps are below.
Check it’s genuine
Is that “your files will be erased” email real?
Microsoft really does send warning emails when your storage is full or your account is heading for a freeze — and because everyone knows that, scammers copy them almost pixel-for-pixel. The scary email in your inbox could be either.
The safe habit is simple: never click the links in the email itself. Instead, open your browser and type account.microsoft.com yourself, sign in, and look at the storage meter. If you’re genuinely over the limit, you’ll see it there in red — no email required. If the meter looks fine but the email insists you must “verify your account” or pay immediately, delete it.
While you’re in there, it’s a good moment to check your account security generally — our guide to securing your Microsoft 365 account takes about ten minutes to follow.
The fix
Get back under the limit — fastest wins first
You don’t need to delete everything — you need to find the handful of things eating the space. In order:
- See what’s using the space. Sign in at onedrive.com, open Settings, and look for the storage summary — it breaks down what’s taking the room and can list your largest files. Nine times out of ten it’s videos and phone camera backups.
- Move the big stuff off. Download the biggest files to your PC or an external drive, check they open, then delete them from OneDrive. One caution: a file with a little cloud icon next to it is an online-only placeholder — it holds no data on your PC. Download it properly (or right-click > Always keep on this device) before you delete the cloud copy.
- Turn off camera upload if you never meant it. The OneDrive app on your phone quietly backs up every photo and video by default on many setups — lovely until it fills 5GB. Move the photos somewhere deliberate, then switch the upload off.
- Clear out jumbo email attachments. They count against the same 5GB pool. In Outlook.com, sort your mail by size and delete the old messages with huge attachments (save anything you need first).
- Empty the OneDrive recycle bin — this is the step everyone misses. Deleted files can carry on counting against your quota for up to 30 days until the bin is emptied. On onedrive.com, open the recycle bin and empty it.
- Then wait a little. Microsoft says storage changes can take up to a couple of hours to register. Don’t panic-delete more because the meter hasn’t moved in five minutes.
Unfreezing
Account already frozen? How to unfreeze it
If you’ve had the freeze notice, go to onedrive.com in a browser and sign in — you’ll be walked through your two options: get back under the limit by deleting files, or buy more storage. Either path unfreezes the account.
Before you delete anything, remember that read-only still means you can download everything. If there are irreplaceable files in there — family photos, business records — take a copy onto your own PC or an external drive first, belt and braces. (Frozen accounts are also a sharp reminder that OneDrive sync is not the same thing as a real backup — here’s why that distinction matters.)
Once you’re under quota or you’ve added storage, allow up to a couple of hours for the account to thaw and email to start flowing again. If your freeze email mentioned a deadline date, please don’t leave this to the last day — the six-month deletion clock is the one part of this with no undo button.
Stuck at any step — wrong account, can’t sign in, meter won’t budge? That’s a ten-minute job for us by secure remote session from £20. We call before we connect, and you watch everything we do.
The decision
Buy more storage, or fix it properly?
Once you’re unfrozen, decide how you’ll stop this happening again. The honest comparison:
- Tidy up every few months (free). Works fine if photos were the culprit and you’ve turned camera upload off. Costs nothing but your time — and it will creep back if you don’t.
- Pay Microsoft for more storage. A storage add-on or a Microsoft 365 Personal subscription (which includes 1TB) makes the problem go away for a monthly fee. Prices change often enough that we won’t print them here — check microsoft.com for the current UK figures before you buy, and only ever buy from Microsoft directly.
- For a business: have someone watch it for you. On our managed Microsoft 365 service at £4.85 per user, per month, storage quotas, licences and renewals are monitored — nobody on it ever finds out about a full account from a bounced invoice. Broader cover starts from £24.38 per computer on our business support plans.
- For a home PC: our home support plan is £18.25 per computer, per month — we keep an eye on things like this, and you get a written Service Report after every session so you can see exactly what was checked.
We’ve supported Microsoft accounts and software since 1995, and taught it for over 10 years at our own Dorset Microsoft Education Resource Centre — so when we say the storage-full trap is one of the most common calls we get, it’s from experience, not a script. We’re remote-first with free local collection if a machine ever needs hands-on work; there’s no walk-in shop, and we meet at Kinson Community Centre by appointment.

// GOOD QUESTIONS
Frequently asked
Will Microsoft really delete my files?
Not immediately, and not without warning. Go over your storage limit for around three months and the account can be frozen (read-only). Microsoft says that after around six months frozen it may delete your OneDrive and everything in it — and once deleted, those files are non-recoverable. “May” is not a promise it won’t, so treat the freeze notice as your deadline to act.
My mailbox isn’t full — so why can’t I send or receive email?
Because a free Microsoft account has a shared 5GB cloud storage pool covering OneDrive files and email attachments, separate from the 15GB mailbox allowance. Once that shared pool is over quota, Outlook.com stops sending and receiving email even if the mailbox itself has plenty of room, and incoming messages are returned to the sender.
I’ve deleted loads of files but I’m still over the limit. Why?
Two usual reasons. First, deleted files can keep counting against your quota for up to 30 days until you empty the OneDrive recycle bin — empty it at onedrive.com. Second, Microsoft says storage changes can take up to a couple of hours to show, so give the meter time before deleting anything else.
What does a “frozen” OneDrive account actually mean?
Your existing files go read-only: you can still open and download everything, but you can’t upload, edit or sync, and Teams messages with attachments are blocked. Frozen is not deleted — it’s Microsoft applying the handbrake until you get back under the limit or buy storage.
How long does it take to unfreeze my account?
Once you’re back under the limit (or you’ve bought more storage), Microsoft says the change can take up to a couple of hours to apply. Email starts flowing again once the account is out of the red.
How do I know the “your files will be erased” email is genuine and not a scam?
Never click the links in the email. Type account.microsoft.com into your browser yourself, sign in, and check the storage meter. A genuine problem shows there in red; if the meter looks fine but the email demands urgent action or payment, it’s a fake — delete it.
How much storage do I actually get for free?
A free Microsoft account includes 5GB of cloud storage shared between OneDrive and your email attachments, plus a separate 15GB allowance for the Outlook.com mailbox itself. Paid Microsoft 365 plans include far more — Microsoft 365 Personal comes with 1TB.
Can you just fix this for me?
Yes. We fix full and frozen OneDrive accounts by secure remote session from £20 — we call before we connect, you watch everything, Mon–Fri 9–5. Businesses that never want this again can move to our managed Microsoft 365 at £4.85 per user, per month, where storage and licences are watched for you.
Should I just stop using OneDrive instead?
You can, but do it in the right order — done wrong, you can strand files in the cloud or empty your Desktop and Documents folders. Our guide to leaving OneDrive without losing files walks through the safe sequence step by step.
Never want to see this error again?
On our managed Microsoft 365 service (£4.85 per user, per month) storage, licences and renewals are watched for you — so a full account never gets the chance to bounce your email. Family-run, supporting Microsoft software since 1995. Mon–Fri 9–5 on 01202 775566, or text 07520 615332.
