I'm trying to remove an unwanted mailbox set of folders from my Outlook navigation pane. I am familiar with adding and removing additional mailboxes to my profile using the "Open these additional mailboxes" section of the Advanced tab in the Microsoft Exchange Server settings window in Outlook. Let's say my primary exchange account and its associated mailbox is "uncbrian." My problem is that Outlook is opening an additional mailbox called "donate." When I try to close it by right-clicking on its top-tier in the navigation pane, Outlook tells me "this group of folders is associated with an e-mail account" and then provides the instructions for how to remove it as I described above. However, the particular account is not listed there. Presently there are no additional mailboxes listed in the add/remove additional mailboxes window. If I "Add" the donate mailbox, I just end up with two sets of "donate" folders in my navigation pane. When I "remove" it again, I'm back down to one.
In "donate's" Active Directory settings, uncbrian has full mailbox access and delete storage privileges. If I remove my priviliges, "donate" still appears but I can't open it. At first I wondered if somehow it were added at the server level, but, for one, I don't know how to do that, and two, the mailbox only shows up on my computer, not on other workstations where my profile is configured. I tried completely removing my exchange account from outlook, deleting all outlook related files in my windows profile outlook application data folder, and then setting up my outlook profile again, but it was still there. Before I either completely erase my windows profile or reinstall outlook, I wonder if you have other suggestions, such as a change in the bowels of the registry.
