Exchange Room Resource Name Change

[rajezhil]

We have Room resources on Exchange online which were migrated from on-premise exchange server, last year we completely migrated the on-premise exchange to EXO, now when we had to change the names of these room resources due to some relocations of the meeting rooms, we had to rename it from the on-premise ad since it is syncd.

I have just renamed the AD object property(display name, SMTP etc), and once it is syncd via AAD, now could see the new name from the EXO but when we use Get-Mailbox -Identity via Exchange online powershell its still showing up the old name, is there any other on-premise ad attribute which needs to be changed?

Make sure you are looking at the correct property, Name and DisplayName are two different ones.

Display name is fine, trying to update the Name attribute which is still showing the old name.

Please review below command.

Set-Mailbox Room1 -Name Room01

[#5]

Write-ErrorMessage : |System.InvalidOperationException|The operation on mailbox "Meeting Room W" failed because it's out of the current user's write scope. The
action 'Set-Mailbox', 'Name', can't be performed on the object 'Meeting Room H' because the object is being synchronized from your on-premises organization. This
action should be performed on the object in your on-premises organization.

Error, which is expected since the room resource was migrated to EXO last year and we have only AD object which is synced from on-premise AD and the mailbox is sitting on EXO.

Any other method to rename it on on-premise AD?

Try renaming the account in the Active Directory Users and Computers console!

Thats the first thing we did, only problem is we couldn't find a way to rename the name attribute for its mailbox.
