I want to delete an entire folder of emails (130,000).  When I attempt it, the site appears to be thinking about it but never does it.  The top of the screen then says "There was a problem with the Outlook service (a temporary network connectivity issue that has nothing to do with your computer).  Please try again. If you keep seeing this message, go to Service Status to check if there's a problem with Outlook."

The Service status page always indicates that everything is working fine.
