User here is trying to do a mail merge, and send as an e-mail address that is in fact a mail enabled public folder, not an e-mail account.
We have tried using profiles within outlook but when attempting to associate that profile with that e-mail address, it asks us for credentials we don't have since it is not an actual e-mail account.
We have also gotten close by within outlook selecting actions, new mail using, microsoft word, and putting the e-mail address (GTA) in the from field which it accepts. Upon doing a test merge, the e-mail came from the user's account, not the GTA e-mail address we told it to.
Any help would be much appreciated. Thank you.
