Hi Alex,
Thanks for your reply. The reason why I did not included any error messages in the first place is because I thought I would not be the only one making use of these possibilites.
This is the error:

It sais it cannot find the recipient. But the email adress is active. Also: office365 connects to the server with no errors. So from the point that Office365 wants to deliver the actual mailbox (routing?) it doesn't work.
If you have any suggestions, let me know.
