I've setup exchange Server 2013 to allow sendas & send behalf of via distribution group for 1 user. I can go in OWA, show from, find the distribution group and mail just fine. In outlook, I can show from, select the distribution group and mail just fine.
Problem: After I send test e-mail to my e-mail and I reply back. The outlook will have auto-complete of the e-mail for a quick way to send mail. Problem is, I don't think outlook 2013 uses the distribution group address book. Once I attempt this, I get an error code 0x80070005 from a non delivery mail.
I've already attempted fixes via google so now I'm looking for someone who had experience with this issue and know how to fix it right away.
