How to Recover OneDrive Files After Changing a Microsoft 365 Email Address
Question details
The user needs to recover missing OneDrive for Business files after their Microsoft 365 work email address was modified.
- Product
- OneDrive for Business
- Device & OS
- not provided
- Scenario
- A Microsoft 365 administrator changed the user's work account email address, causing associated OneDrive files to appear missing.
- Observed behavior
- All OneDrive files associated with the old email address disappeared after the username was changed.
Ensure you have the exact new email address and password provided by your organization's Microsoft 365 administrator, and close any existing browser sessions.
Locate Files Using an Incognito or InPrivate Browser
Because a username change updates the OneDrive URL, old cached credentials might prevent files from showing. Use a private window to force a fresh connection.
Changing a username does not normally delete OneDrive content, but it does change the underlying SharePoint URL. Browser caching can sometimes hide your existing files or fail to load the new URL correctly.
Launch your web browser and open a new InPrivate (Edge) or Incognito (Chrome) window to bypass cached logins.
Go to the Microsoft 365 portal and sign in using your newly assigned email address and password.
Click on the OneDrive icon from the app launcher. Navigate to 'My files' to see if your data is now visible under the new URL.
If files are missing, check the OneDrive 'Recycle bin' and the 'Second-stage recycle bin' (found at the bottom of the Recycle bin page) to restore them.
Contact Your Microsoft 365 Administrator
If files are still missing from My Files and both recycle bins, your IT administrator must intervene before the time limit expires.

Frequently Asked Questions
Does changing my Microsoft 365 email delete my OneDrive files?
No, changing a username or email address normally only updates the underlying URL of your OneDrive for Business account. It does not automatically delete your files, though they may temporarily seem missing due to browser caching or background syncing.
Why did my files disappear after my organization changed my email?
Because the OneDrive URL is based on your email address, the old URL becomes invalid. If your browser or desktop app tries to access the old cached URL, it will fail to display your files. Logging in through an Incognito or InPrivate browser window usually resolves this synchronization issue.
How long do I have to recover deleted files in OneDrive for Business?
Files deleted in OneDrive for Business are kept in the first-stage recycle bin for 93 days. If removed from there, they enter a second-stage recycle bin for the remainder of the 93 days. If files are entirely lost due to a provisioning error, you must contact Microsoft Support via your IT admin immediately, as backend recovery is highly time-limited.
