We desperately would like the option for users to logon on to a mailbox by using the credentials of another account. Whether this be a resource account, or in one of my customers cases - accounts positions are consistently named and linked to disabled mailboxes, user accounts (since the users are transient) are seperate and not mail enabled. I.E. The poisition and the user account are "divorced" from each other with the user account having mailbox rights and send as on the position mailbox.
something as simple as a check box under the username/password that says "My account is my mailbox". Uncheck it and another text box slides open on the screen which allows one to put in the alias of the mailbox that they truly want to logon to.
Today we have written a custom ASP page that authenticates and looks up the alias they want to use (either by them typing the alias or the SMTP address - since that is what they did in the 5.5 OWA), and then it formats the URL to be mail.company.com/exchange/alias . The reasons we want to move away from this are:
1. No desire to support home grown code if it isn't necessary.
2. Users have to go through 2 "screens" to get to their mailbox even though it is a necessary evil. We would like to get down 1 screen to simplify their lives.
Thanks for this consideration as I think other people out there would like to have the option to logon to a seperate mailbox they have permissions to - especially if their own account is not mail enabled.
