In Exchange 2010, you could go to recipient configuration>mailbox and on the top of the screen filter mailboxes, groups and other items by using filters: Equals, Does Not Equal,Contains,Does not contain, Starts with, Ends with, among others. This relatively simple search feature was invaluable as an Exchange administration tool.
This functionality seems to have been removed in 2013, why? I have no idea, but can someone please tell me how I can search? I want to find all mailboxes that contain a certain keyword. Again, very easy in 2010, 2013 not so much.
And no, I do not want to use powershell to do so, it's counter intuitive to obtain a list of mailboxes and then have to go back into another screen to make modifications.
