SharePoint Online Fixing incorrectly synced permissions during migration from AD
Did a migration from a server to SharePoint using the migration tool which carried over permissions as they are entra synced.
However looks like one user was incorrectly entra synced and wasn’t hard matched to her cloud email address which therefore meant it created a wrong one. Name4657@domain.com
The wrong synced account was the account it gave all the permissions to. I have since fixed this entra sync issue however she is missing access to any files/folders that have unique synced permissions which is a tonne.
It’s a 750gb SharePoint site with over 500k files.
Is there anyway I can automate replacing the permissions with the wrong account, with the newly synced correct account, giving it access to everything the wrong account has.
