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 signature is 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?

We are suffering from the same problem and this is affecting a huge portion of our Production users. Some guidance from MSFT would be greatly appreciated!!
Having the same issue. Nice to hear it's not just us. I assume the changes haven't been built into the Powershell module yet???
No response from MSFT?
You can also add to / follow the thread on StackOverflow here: https://stackoverflow.com/questions/69764573/change-signature-in-outlook-web-owa-with-powershell or my GitHub bug report here: https://github.com/MicrosoftDocs/office-docs-powershell/issues/8537

I suggest you also open a support ticket (we have too) as Chris Davis from MSFT suggested on my issue here: https://github.com/MicrosoftDocs/office-docs-powershell/issues/8537#issuecomment-962059190
I already raised a ticket at Microsoft in June, when the first time was, they changed the OWA UI and added the "multiple Signature" feature, but not update the set-mailboxmessageconfiguration CMDlet. Like every time, you need to discuss this hundreds of times with Microsoft and they do just "keep the customer busy" programs in their support. After a few weeks of discussion, they rolled back the OWA Update and everything worked fine. Now again, they updated the Servers with the new OWA Version for multiple Signatures and the set-mailboxmessagconfiguration command is broken again. Again, Microsoft Support is just discussing and wants to have fiddler LOGs or PSR for a Microsoft Server issue. The problem is, MS itself don't understand their technic and the support is just a "keep the customer busy" machine, without any help. It is disgusting, how much Microsoft hates their customers and like disabling their business. Please, if you have that issue, cause of the new OWA API for multiple Signatures, create tickets at MS. Thank you.
