The same goes for us.
However, the other way around it works. If the address *@primarydomain.com does already exists, it will not be created in the new mailbox afterwards.
For now, we use a hidden distribution list, were we first create the not used alias @primarydomain.com, so that when it is needed, we can create a single address from it.

I did it now with a Powershell Script too.
Add small image to AD
AD sync to AzureAD
Add bigger image to Exchange
But if the limit would be at least 100kB, the same as Azure, you could at least try to use just one command and photo, not two differents.
