Hey Guys,
thnaks for your answers!
I checked our server and migrated Users again and recognized that the missing mailbox simply got a new email address whatsoever and hide it's real name between other mail addresses^^
The new primary address isn't even present in the proxyaddresses attribut in the on-prem AD and is even set to another shared mailbox in the AD.

Have a nice week!
