Have Exchange 2013 installed with CAS/Database roles. Right now mail still flows through 2010 and no mailboxes have been moved. I am testing the setup for mail and Outlook access to go through the Exchange 2013 server. When I first login to the network get a prompt from Outlook for password. If I close and open Outlook get prompted again for password. I have added NTLM to the Outlook anywhere VD along with Basic for authentication. But still get prompted. has any one worked through this before. -- T. Todd Lemmiksoo
