Getting support for something like this at Microsoft is impossible. They don't care at all. They will reply with standard responses from some supporter without any access or knowledge of the inner working of the system.

I do understand the ideer of letting a large IT organisation handle you email. Working email is a high priority, if not Microsoft or Google can make it work, who can?

As more and more are moving their solutions to Microsoft and Google, they will be in a position to strangle any smaller providers.
