This problem has just started occurring.
I have lost connection to Exchange. Outlook 2007 will not connect either in MAPI or POP3 modes.
This has happened a couple of times recently, and eventually, after a number of restarts the connection has come back for a few hours.
This morning, no connection again.
I have re-run the IECW - no joy.
I have checked the Appplication and System event logs and nothing relevant appears to be there.
I have restarted the server - no joy.
I have checked other access to the server - it pings ok, I can connect via Remote Desktop etc.
I've done an IISRESET.
I'm at a loss to explain this particularly as there are no apparently relevant event log entries.
