Brian,
btw, we did open a case with MS support. The first one resulted in a no-charge bug find for the move mailbox issues. The POP issue took 3 MS engineers over 8 hours to finally find, and again we weren't charged due to it being classified as a bug. The redirect and other issues we spent hours looking for on the Internet and asking peers and the methods (ex. delete the web.config?) seem really outlandish.
I'd say at least 24 hours were wasted trying to resolve bugs. We put in 2 calls to Microsoft PSS in order to fix bugs. The customer still isn't completely satisfied, but that's mostly because they hate the look and feel of OWA. The end-users are telling management they feel it's a step backwards from Exchange 2007. Crazy.
