Moi Matti,
The problem is that when you create a shared mailbox, the alias with the local name is also created. Thus, regardless of the domain part, you have the error you described.

I found the option to type the alias. But I get this error:
The proxy address "SMTP:asiakaspalvelu@domain2" is already being used by the proxy addresses or LegacyExchangeDN of "Domain 1 display name". Please choose another proxy address.( The "UserMailbox" with display name "Domain 1 display name" is already setup and using the same address.)

Are both the name and alias of the domain2-mailbox you try to create unique?
