Hello AD/Exchange experts.<br />
I am setting up a new DC/Exchange 2013 Server for a company with several split businesses and email domains. Here is my question.<br />
<br />
I would like all users to login to OWA using their SMTP email address and NOT the AD Domain Name.<br />
<br />
I setup a new Windows 2012 DC with the AD Domain as COMPANYX.COM and I can get all users to login with username@companyx.com however I am not able to have them login using the SMTP address (ie. username@comanyXYZ.com).<br />
<br />
Is this possible to accomplish out of the box ? I have no problem with email flow, I have setup multiple authorize SMTP policies and setup the appropriate reply-to addresses with no issues, I am just struggling with the AD authentication portion.<br />
<br />
Thanks
