User is unable to login to Mailbox
Hello experts,
We are in Hybrid environment and one of the user which was recently re-enabled an AD account as the user is returned back to us, is unable to login to mailbox
Steps we done
Re-enabled the AD account and moved it to syncing OU and added license to enable mailbox
I checked the recipient details in both on-prem and online
On-prem results
RecipientType : MailUser
RecipientTypeDetails : RemoteUserMailbox
Online results
RecipientType : UserMailbox
RecipientTypeDetails : UserMailbox
What is the part that is missing here.

Hoi Mani333
Try this:- Remove the User from the Entra Sync Scope
- Wait for Entra Sync to complete
- Remove the User in Entra from the Deleted Users
- Set-User <Mailbox> -PermanentlyClearPreviousMailboxInfo
- Add the User to the Entra Sync Scope
- Wait for Entra Sync to complete
- Make sure Mailbox is available in Exchange Online (Get-Mailbox) and has License
Kind Regards

Is there any chance of losing the users mailbox or one drive data during this process

Its also worth checking if the users onedrive data got restored after you re enabled the user. Do you get any correlation ID error when you click the mail tab of this user in the M365 admin center?
