Wanting to know how to solve failed to disable the mailbox due to a conflict in directory settings in Microsoft 365 mailbox? You’re in the right place.
I noticed the same error on a user account and was not sure of appropriate steps to get rid of the error and followed some steps as per Google but in vain. Fortunately, I fixed it using the the following steps.
Before we begin, check the recipient type of the affected mailbox in Exchange Online powershell.
Great, the recipient type is user mailbox. It’s a time to export the mailbox content as pst file and disable the mailbox in on-premise using the (disable-mailbox test248) command.
Wait until the changes replicate to O365. Once it is synced, enable the on-premise object but the recipient type should be a remote user mailbox.
Enable-remotemailbox “test248” -RemoteRoutingAddress email@example.com
Wait for the sync again and assign the Exchange Online license to the user account and check the status.
The failed to disable the mailbox due to a conflict in directory settings message is disappeared now. Finally, import the pst to the user mailbox.
