Exchange server is a 2008 standard server. Request was for users to be able to log on why Web access using the mail.wcf.ca url
for both internal and external for. I used powershell Exchange to change OWA, ECP,OAB and the Microsoft-Server-ActiveSync settings to mail.wcf.ca for both internal and external. I also set Web Services for both internal and external to mail.wcf.ca and did a Autodiscovery to this setting. I did screen printouts just to make sure I could change it back but not find that the Exchange powershell is unable to find server WCF2010Mail. Is there a back door to make these changes back to the original settings.
Not that experienced and need all the help I can get.
