I have an open question about how to set up Send AS ( https://www.experts-exchange.com/questions/29008980/Exchange-Sending-On-Behalf-does-it-work-with-secondary-emails.html
) but now it is all setup but there is a weird bug in it: I log on 2 different computers with the same username and do the same "send as" and on one computer it doesn't work and the other it is working...???
I closed Outlook = same problem, I closed the computer and relog in and it is still doesn't work.
If it was Permissions issues why would it be working on one computer?
I have log on 2 different computers where that user never logon and the sent as was working...! His computer runs Office 2007 and the other 2 Office 2010, could that be that? Or is it because his profile was created on the other computers for the first time when doing my test while on his real computer, it always have been there.
