Hi @Carter009
If the user has many account , you should :
- Start by identifying all users with multiple accounts
- Ask users to migrate o365 data (Mailbox, Onedrive,Teams history) to a single account.
User should be able to export all datas (email onedrive) and save on his desktop and then import them using another account - Once all user date are moved to single account , you can move other accounts to unsynced OU to delete Entra account and the o356 licence will be removed automatically.
Please don't forget to accept helpful answer
