How to Fix SharePoint Sharing Errors When Reusing an Email Address
Question details
Users encounter errors when trying to access SharePoint shared links using an email address that was previously assigned to a deleted employee.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- A new employee is assigned the email address of a former employee, but sharing links fail to grant access because SharePoint still recognizes the old user's identity.
- Observed behavior
- The current user cannot access shared folders and files via sharing links, despite having normal OneDrive access, because the document permissions reference the deleted user.
Ensure you have SharePoint or Microsoft 365 admin center access, and verify that the former employee's account was completely removed before applying these fixes.
Update Permissions and Generate a New Sharing Link
Remove the former user's identity from the file or folder permissions and share the content directly with the new user.
SharePoint relies on unique internal identifiers rather than just email addresses. You must manually clear the old user's permissions from the file so the system recognizes the new user.
Navigate to the file or folder in SharePoint Online. Click the three dots (More options) next to the item, select 'Manage Access', and remove any existing permissions associated with the reused email address.
Click the 'Share' button on the document or folder and enter the current user's Microsoft 365 user principal name (UPN) to grant access.
Create a new sharing link via the 'Copy link' option and send it to the new user to verify they can access the content successfully.
Create and Set a New Alias for the Affected User
If permissions continue to conflict, create a new primary alias for the user to force SharePoint to recognize a distinct identity.

Frequently Asked Questions
Why do SharePoint links fail when an email address is reused?
SharePoint links and permissions are tied to an internal user identifier (like a PUID) rather than just the email address. When an email is reused, SharePoint may still associate the link with the deleted user's unique identity.
How long does it take for SharePoint user profiles to synchronize?
It typically takes between 4 to 24 hours for changes made in the Microsoft 365 admin center, such as adding a new alias or changing a primary email, to fully synchronize across SharePoint Online.
Will changing a user's primary alias prevent them from receiving emails?
No. As long as the original email address remains listed as an active secondary alias on the user's account, they will continue to receive all emails sent to that original address.
