Here is my issue... I am going through the mail settings and when I enter my external domain name and then I put in my user name it resolves the user and changes the domain name from exhange.domain.com to exch01.domain.local... I then when into the advanced features and forced the use of FQDN by using outlook Anywhere it connects to the server. It then prompts for the username and password... When I supply it, it just bounces back.. I changed the setting on the Default Global address list and now it works... But When I remove it, it does not work.. I have 3 gals... domain1 GAl, Domain2 GAL, and default GAL...What do I need to change to get it to work with the other GALs? Something is forcing it to the default GAL...

Could you please check your Exchange connectivity? https://www.testexchangeconnectivity.com/ Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Hi,As my understanding that you can configure the profilein outlook anywhere,but you cannot login,is that ture?If yes,then I'd like to know what is the settings that you have changed on Default GAL?Please try to use get-exchangecertificate |fl to check the certificate that you have used for Outlook Anywhere.Besides,how many CAS servers in your environment?Did you publish CAS servers or make NLB on CAS servers?Regards,Xiu
