I am currently working on a migration from Exchange 07 to 2013. My current DNS setup is as follows:
Internal server name: EXCHANGE
External DNS for OWA and smartphones: webmail.abc.com
MX record: mail.abc.com (Which points to barracuda spam device)
My question is what DNS entries do I need to configure for the new server to work internally and externally.
Also, as a side note I have a mixed environment of Windows XP and Windows 7 workstations ALL running Office 2010. The reason I mention this is because I am having issues with XP machines connecting to Exchange 13. My research is saying that XP does not know how to "handle" the SAN certs and so it does not autodiscover successfully and configure the Outlook Anywhere settings. It keeps prompting for username and passwords during setup process and never finishes successfully.
I have purchased a WildCard SSL cert for the production environment, but my lab is failing with the default self signed certs from Exchange.
Any help would be greatly appreciated......
