I lost 7 years of files when Microsoft thought my 365 account had expired. How to recover?

If the Microsoft 365 subscription tied to the original email address expired and the associated OneDrive/SharePoint storage was cleaned up, recovery options are limited to what is still retained in Microsoft’s services.

Follow these steps in order:

1. Sign in with the original (expired) account
   Even if a new subscription was purchased on another email, the old data is tied to the old account/tenant.
   • Go to the OneDrive website and sign in with the old Microsoft account (the one that expired).
   • If sign-in still works, proceed with the checks below.
2. Search for files in OneDrive (old account)
   • On the OneDrive website, use Search everything at the top of the page to look for key words, file types, dates, or locations (for example: xls, doc, sales, 2019).
   • For work/school accounts, follow the guidance under Work/school → Search for your files on the OneDrive website.
3. Check the OneDrive Recycle Bin (old account)
   If the subscription expired and content was deleted, it may still be in the OneDrive Recycle Bin within the retention period.
   • On the left side of the OneDrive website, select Recycle bin.
   • If the missing items appear, select them and choose Restore at the top of the page.
   • For personal accounts, if Personal Vault was used, select Show Personal Vault items in the recycle bin after unlocking Personal Vault.
   • For work/school accounts, also check the Recycle Bin as described in the Work/school section.
4. Check for files under a different Microsoft account
   Since the new subscription is under a different email address, confirm that the files are not actually stored there:
   • Sign out of OneDrive, then sign in again with the new Microsoft account.
   • Search for the files and check that account’s Recycle Bin as well.
   • If multiple personal or work/school accounts exist, repeat the search and Recycle Bin checks for each.
5. If files are not in OneDrive or its Recycle Bin
   • For a personal OneDrive account that has been inactive for two years, the account and its data may have been deleted.
   • For work/school OneDrive, deleted files are typically retained for up to 93 days; after that, they may no longer be recoverable using native tools.
   • If using a work/school account, contact the Microsoft 365/SharePoint admin to see if they can restore items from the SharePoint/OneDrive recycle bins or from any tenant-level backups.

If none of the above steps show the files in OneDrive, its Recycle Bin, or another account, there is no documented native Microsoft method in this context to recover data that has already passed the retention window and been permanently deleted from the service.
