I'm posting this to help others who may experience the same problem. I own a D-Link DIR-615 (Rev. C) wireless-N router. Upon updating the router's firmware to version 3.12NA, Outlook (on all my computers) started losing the connection to Exchange Server. This continued for approximatley 2 weeks and stopped happening immediately upon reverting the firmware to version 3.11NA. I'm running Outlook 2007 on all computers and they are set to connect to Exchange via HTTP.

If it were me, I'd roll back to the previous version of router firmware. -- Ed Crowley MVP "There are seldom good technological solutions to behavioral problems." .
