What happens to your school Microsoft 365 account after you leave

The lifecycle of a school Microsoft 365 account from your last day to permanent deletion — typical timelines, what survives, what doesn't, and what to do about it.

Almost every student who loses school work loses it for the same reason: they assumed the account would stay alive longer than it did. This post is the lifecycle of a school Microsoft 365 account, end to end, so you can plan around it instead of being surprised by it.

The five stages

Every school M365 account goes through the same five states, in order:

  1. Active: you're enrolled, you sign in, everything works.
  2. End of enrolment: your formal leaving date. Account still works.
  3. Deactivation: IT disables the account. Sign-in fails. Data still exists.
  4. Soft delete: account is in a recoverable state for a defined window. You can't reach it, but a tenant admin can restore it.
  5. Hard delete: account and data permanently removed. No recovery path.

The five stages are universal. The intervals between them are not.

Typical intervals by institution type

Secondary schools (Year 7 to Year 13 in the UK, K-12 elsewhere): deactivation usually happens 30 to 90 days after the final exam window. The summer is busy for IT teams handling re-marks, late submissions, and onboarding the next cohort, so leaver deactivations tend to get queued for August or September. Soft-delete window: typically 30 days. Hard delete after that.

Sixth-form colleges and post-16 institutions: similar to schools, but often slightly faster because there's no in-house lower-school cohort to consider. Account closure often falls within 30 to 60 days of results day.

Universities and colleges (higher ed): more variable. Many cut OneDrive and OneNote within 30 days of graduation while preserving alumni email on a downgraded mailbox. Some preserve full access for a longer transition window. Research universities often have separate retention policies for research data.

Independent and private schools: tend toward the faster end of the range, often closing accounts within 30 days of the academic year end.

What survives, what doesn't

When the account hits hard delete, the following disappear permanently:

  • OneDrive and everything in it (every file, every folder, every version).
  • Personal OneNote notebooks.
  • Class OneNote notebooks (your section group).
  • Outlook email (unless an alumni mailbox preserves it).
  • Teams chats and channel-shared files you'd uploaded.
  • SharePoint site memberships and the access tokens to view shared content.
  • Any third-party SaaS app you signed into using your school account that uses Microsoft sign-in (you'll get logged out, and re-login will fail).

What survives:

  • Anything you downloaded before deactivation.
  • Alumni email if your institution offers it.
  • Public records the institution holds separately (transcripts, certificates) requested through the appropriate office.
  • Things you'd already moved to a personal account before leaving.

The soft-delete trap

Soft delete is the most misunderstood part of the lifecycle. When IT deactivates your account, the data is still there for a brief window — usually 30 days. People assume this means "I can ask the school to get it back if I forgot something."

In practice, schools rarely restore deleted student accounts. The IT workload of restoring an account, helping the former student extract what they need, and re-deactivating is not insignificant; the headline reason most schools don't do it is that they have no obligation to. The soft-delete window exists for IT to fix administrative mistakes (oops, deactivated the wrong account), not for ex-students to retrieve forgotten data.

Once hard delete runs, there is no recovery path. This is a Microsoft architectural constraint, not a school policy choice. Even with a paid Microsoft Support escalation, a hard-deleted account stays gone.

What you should do, and when

During your final term (before any exam season): start thinking about what's on your account. This is the cheapest time to download — you have time, the account is fully active, you're at school with school Wi-Fi.

In the final fortnight of term: do the export. Either use a self-service tool (mydocs.school exists exactly for this), or do the manual export — OneDrive web download, OneNote per-notebook export, OneDrive desktop sync to a personal computer.

By results day: have at least one backup of everything you care about. Two copies in two locations is the safer default.

Within 30 days of formally leaving: if you missed the in-term window, do it now. Your account is probably still active but it's running on borrowed time.

Past 90 days: assume the window has closed unless your school explicitly told you otherwise.

The things people regret losing

Anecdotally, the work alumni come back asking for and can't recover, in approximate order of frequency:

  1. Class OneNote notebooks — particularly subjects where the teacher annotated heavily.
  2. Coursework drafts — earlier versions of essays and projects, useful for portfolio evidence.
  3. Personal OneNote revision notes — the work that powered the run-up to exams.
  4. Group project documents — useful as evidence of teamwork for applications.
  5. Photos and scans — whiteboard captures, art portfolio shots, fieldwork data.
  6. Older sent emails — particularly to teachers about specific topics that come up again.

Most of this never feels important at the time. Most of it becomes useful in the two-year window after leaving.

Per-workload guidance

If you want the detail per workload:

What to do if you've already left

If you're reading this after your account has already closed, two things are worth trying:

  1. Email your school's IT team and ask politely. The answer is often no, but it's sometimes yes — especially if it's within the soft-delete window and you can be specific about what you need.
  2. Ask the people you worked with directly. A teacher might have a copy of your coursework. A friend might have the group project document. A society lead might have the presentations from the talk you co-wrote.

If you're still enrolled and reading this proactively: take an hour this week. Future-you will be glad.
