Cannot create Shared Mailbox or E-Mail Alias

[WinstonNau]

Hello,

I recently moved my company emails to Microsoft 365 and I now have some trouble with creating new emails, even though my main email is already working without any problems.

When trying to create a shared mailbox, I get the following error:

 

Trying to create an email alias also results in an error:

Does anyone have experience with this error or is able to give me some advice on how to resolve this?

Best regards

Winston

The second error should be a transient one (i.e. try again in few mins), but the first one looks like an issue on the backend, so best open a support request.
