Exchange 2007 Congestion Problem
Sometime during the past few hours, the routing connector between Exchange 2003 and Exchange 2007 became congested. This resulted in long delays for mail from inside and outside the district to reach email accounts on Exchange 2007 (there are only about 49 of us, and most people in this group are in Information Technology.)
The cause of the congestion was located and repaired (several files with large attachments were gumming up the connector.) Normal mail flow resumed at approximately 2:30 pm.
