I have exchange on my server it has been working fine for over the last year but as of 2 days it is now saying in my outlook 2007 it is displaying disconnected and it doesnt want to connect. Any ideas how to reconnect to my exchange server
Check your network connection to your Exchange server. Can you ping your Exchange server from your client using the hostname? If you can proceed, if you cannot then you have a network layer issue between your client and Exchange.
Hold down CTRL and right-click the Outlook icon in your system tray and choose "Connection Status". You should see your Exchange server under general and it should say "Disconnected" if you aren't connected. Go ahead and click "Reconnect" to attempt to reconnect.
