Going through a migration. Current Environment is one 2007 Exchange server with all roles on one box. All Clients use Outlook 2007.
Setup a new Exchange 2010 box. (all mailboxes are still on 2007 box, havent cut over yet)
From what i understand, the new 2010 box will proxy all Exchange requests and filter them off to the 2007 environment.
Every time a end user opens up an outlook client, it always asks them for their password, it wont retain the information. Might seem small, but is becoming a big issue. If they put in their password correctly, they can connect to exchange.
I have checked the settings in EMC on both 2010 and 2007, as well as the Authentication settings in IIS on the 2007 and 2010 box.. but cant figure out why.. .the password wont retain.
Tried creating new profiles for the outlook client, still no luck.
Details: Exchcange 2007 = Win 2003 R2 box | IIS6 Exchange 2010 = Win 2008 R2 box | IIS7
Appreciate any info
