Linked Mailbox Authentication
Posted on 2010-08-26
We have recently upgraded a network that consists of two domains (one 2003, the other 2008) that are separate but trusted (a full trust is established between them).
Users on both domains connect to the Exchange 2010 server in the 2008 domain. These users have linked mailboxes on that server, and can log in to the mailbox using their usual username and password.
The issue is that when Outlook is used (for a user with linked mailbox), it always prompts for the username and password when it starts up (even though the user is logged in with the correct credentials). The user has to enter their details in the form domain.local\username with their usual password.
I would like to know how to ensure that these credentials are correctly supplied without the user having to enter them each time. Ticking "Remember Details" does not work.
