Hi @Marvin Oco good morning. 

 

You can do it from Exchange Admin or by Powershell.

Hi, the exchange server on premise is now decommissioned /
Not available. Any other ways? Tnx

Hi @Marvin Oco 

 

If Exchange is already decommissioned, why not you create the Room mailboxes from Exchange Admin portal directly? 

 

Are you using Azure AD connect? 

 

Thanks!

Yes using ad connect. How do we purge the "ad synched room mailbox"?

Hi @Marvin Oco 

 

If you are using Azure AD connect, I presume your Room mailbox was synced in Office 365 as user mailbox. In that case, you can convert this user mailbox to a room mailbox. 

 

You can use exchange online powershell and run "Set-Mailbox YourUser -Type Room"

 

Also, here you can find more info:

I hope this can help. 

 

Good luck!
