Unable to perform the save operation when enabling Exchange Online Archive

Customer wanted to enable the Exchange Online Archive on his Exchange Online Mailbox. Open the Exchange Admin Center, select the user and in the actions pane select “enable” under In-Place Archive.

After a couple of seconds the following error message appeared in the top of the actions pane:

‘The following error occurred during validation in agent ‘Windows LiveIdAgent’: ‘Unable to perform the save operation. ‘User’ is not within a valid server write scope.


I didn’t realize this was a hybrid configuration, and in a hybrid configuration all management takes place on-premises and is then replicated to Office 365 (sigh).

So, logon to EAC on-premises, select the Mailbox (Mailbox Type Office 365) and in the Actions Pane click Enable under In-Place Archive.


When you click View Details you can see more information regarding the Online Archive:


Now wait for replication to occur (or force replication using the Start-OnlineCoexistenceSync command on the DirSync server) and the Online Archive appears in the Office 365 EAC:


Of course it is also possible to create the Online Archive using the Exchange Management Shell, just enter the following command:

Enable-RemoteMailbox -Identity <mailbox> -Archive

So remember (also note to self ;-), all Exchange management takes place on-premises in a Hybrid Configuration!
