When you first go into exchange 2007, and highlight Recipient Configuration\Mailbox is there a way to STOP the auto loading of the users? I don't want to set it a small number of users because when I do a search I don't want that limited. I want it to NOT LOAD ANY USERS AT AND JUST LET ME SEARCH. Every time I go in, I have to wait a few seconds for it to stop loading users, so I can actually search for whom I am searching. I usually hit STOP LOADING, get annoyed, wait, then set a filter to search. This has been annoying me for years, and thought I'd finally ask.

Setup a fake filter (one that returns no results - Name=YadaYada), then go to View > Save Current Filter as Default.

I love you with all my heart.

Glad to be able to help. Best of luck.
