Cant no longer change OWA's signature
Hello all, I am trying to update my Outlook Web's signature with Powershell, like I always do, with the"Set-MailboxMessageConfiguration" command, but the signatureis not updated. But "Get-MailboxMessageConfiguration" shows that the new signature is there OWA allows now for some people/organitations to manage multiple signatures, but I can't find any documentation/information about that. So, how I can modify the already existing signature? Or, how I can create a new signature?
