Hello - we are having recurring episodes with our Outlook 2010/Exchange 2003 going offline and we have to reboot the server to get it working again. Outlook clients will not be able to connect. There does not appear to be any errors that standout on the server, so this is a mystery to us, and are looking for ideas on things to check pertaining to the health of the server, that might help us flush out the root cause. The server OS is Windows 2003. Any ideas would be greatly appreciated.
