Hello Folks,
I have this problem and is making me crazy if anyone have any idea please shed some light on this:-
1. Working Outlook 2010 and 2013 clients with webmail.xyz.com as Outlook Anywhere proxy address.
2. Installed new Exchange 2013 server (server02)with CAS and Mailbox role, Exchange install wizard finished and server is rebooted.
3. Server came up online started changing internal and external FQDN's of Virtual Directories and Outlook Anywhere to webmail.xyz.com
4. As soon as Fqdn's changed some outlook clients create support request that Outlook suddenly white's out and after reopening it is giving error cannot connect to exchange. upon checking Clients Exchange Proxy address is set to http://server02.xyz.com, even though OA/OWA/ECP/OAB/EWS/Autodiscover/ActiveSync FQDN's Point to webmail.xyz.com, on all servers if i create new outlook profile for same user it picks up correct settings through autodiscover and connects fine, this is happening to about 20% of outlook clients every time i am introducing new Exchange 2013 server in Organization. we have around 2000 users and planning on installing 4 exchange servers to distribute load and everytime changing outlook profile of close to 150-200 users is not possible.
Any help is greatly appreciated.
Thanks
Cool
