Outlook RT will not connect to our Exchange Server.  The W8 Mail app connects with no problem and have been using since the start.  It cannot resolve the username and will not connect even though it asks for and accepts my Exchange password.  I contacted Surface tech support and they were absolutely clueless.  No help at all.   Is there anything special that needs to be done on the MS Exchange side for Outlook for RT.  We connect with iDevices and W8 Phones using Activesync with no issues.  I realize this is a "Preview" release but you would think the tech support would at least propose some reasonable fix suggestions.  The support person seemed to be looking on blogs for help while I sat on the phone...dissapointing.
