In our company we have several domains & even several different company names for different products. Right now I set up a default "send-as" address for each person, then they can receive at a bunch of different domains. However, if they open up a new message & change the "from" box to a different email address (ie, firstname.lastname@example.org instead of companya.com), it gives them a permission bounceback error.
Is there an easy, non-IT way to set this up to work? I really want to make sure that everyone can send as any email address that is specified under their "Email Addresses" tab in Exchange (Recipient Policy).
I am sure this is easy, I'm just missing it.
