Your OneDrive Is Frozen: The Three and Six Month Clocks

Of the four major consumer cloud services, Microsoft publishes the shortest runway between going over your limit and losing everything. It is also the only one that uses the word "frozen", which is a usefully accurate description of what happens.

Two numbers run this entire page. Three months to frozen. Six months to possible deletion.

What frozen actually does

Microsoft's description is blunt: you "can't upload, edit, or sync new files", and existing files are read-only.

So the account is not gone and the files are not gone. What is gone is write access. Your computer still shows the OneDrive folder, the files still open, and every attempt to save a change fails.

Then there are two consequences that reach well beyond storage.

Outlook.com email stops. Over the quota, Microsoft states you cannot send or receive email "even if your email storage is fine", and incoming messages are returned to the sender. Someone emailing you gets a bounce. You get nothing, including no indication that anything was attempted.

Teams attachments stop. Messages carrying attachments will not send.

This is why a frozen OneDrive is so often diagnosed as "my email is broken". The symptom appears nowhere near the cause.

Three months, counted from where?

The trigger is documented clearly: the account "remains over its storage allowance for three months".

That is countable, and it means a freeze is almost never a surprise to anyone who was paying attention. You went over, you had a quarter of a year, and the state changed.

The second trigger is much vaguer. Microsoft also freezes an account "if you don't sign in for a long time", and does not define how long. We have listed that below as something the documentation does not answer, because an undefined period is not something anyone can plan around — and it means a dormant account holding old family photos is at risk on a schedule nobody outside Microsoft knows.

Six months, and the sentence that matters

"After six months, Microsoft might delete your OneDrive and all files in it."

Then, immediately after: "You can't recover the files after they're deleted."

No recycle bin. No retention window. No support escalation that gets it back. Compare that with the 30-day recovery window that applies to ordinary deletions, and the difference in tone is deliberate.

Microsoft does not say when the six months starts. From the freeze? From going over the limit? The documentation we checked does not resolve it, so the only safe reading is the pessimistic one: assume six months from the freeze at the latest, and treat a frozen account as a thing with a deadline rather than a thing to deal with later.

Read-only is your rescue window

Here is the practical point that redeems all of this.

Frozen means read-only — and read-only means you can still get everything out. Downloads work. The sync client can still pull files down. Nothing stops you taking a complete copy on the day you discover the problem.

So the correct first move on seeing a freeze is not to start deleting things to get under the limit. It is to copy everything to a local disk, confirm the copy is real, and only then decide what to remove.

That ordering matters because deleting under time pressure is how people remove the wrong things. Our OneDrive exit report covers the limits on getting data out in bulk — including that OneNote notebooks never come down in a download, and that browser downloads cap at 20 GB overall, which is why the sync client is the right tool for a rescue.

Getting it unfrozen

Free up space or buy storage, and the freeze lifts. Microsoft notes two timings worth knowing before you panic a second time:

• Changes can take up to 24 hours to apply.
• If it is still frozen after 48 hours, contact support.

People delete 50 GB, see no change in ten minutes, and conclude the deletion did not work — then delete more. Give it the day.

What the documentation does not say

• How long "a long time" without signing in is, before that trigger applies.
• When the six-month deletion window begins — at the freeze, or at the moment you went over.
• Whether any notice is sent before deletion, and how many warnings.
• Whether files in a shared Microsoft 365 Family subscription follow the subscription owner's clock or the individual member's.

These are open questions, not criticisms. Where Microsoft does not publish an answer we say so rather than inventing a plausible one — and on a page about deletion deadlines, a confident wrong number would be worse than no number.
