I need to set up two mailboxes with activesync on my android device. both accounts are on the same mail server in the same domain. also, if I have mailbox rights on another account with send as permissions, how can i select the "from" email to toggle which exchange email address I want to send from. I know i can do this in outlook 2010 and in owa from exchange 2010. How can i do this with android activesync?
