You mean they disabled the remotemailbox on-prem, right? But the AD account is intact?
You can always re-enable it on-prem in that case.
Enable-RemoteMailbox <username> -RemoteRoutingAddress username@<tenant>.mail.onmicrosoft.com

Then set the SMTP addresses as required on the remote mailbox as required and wait or force the AADConnect sync to 365...

Hi Andy,

Correct, AD user is intact and mailbox data looks to be also intact in the cloud. I'll test your solution, our goal is to not loose data of the user mailbox and be able to see the remote-mailbox on the onpremises server.

I'll update soon.

Regards.
