Are you having the “outlook cannot log on. verify you are connected to the network” error? Did you just recently have a DNS or Active Directory issue?
One of the reasons why you might get the “outlook cannot log on. verify you are connected to the network” error is when there is a setting missing in the “Microsoft Management Console”. I recently worked at a client who’s PDC went south big time. Long story short they were getting the “outlook cannot log on. verify you are connected to the network” error every time they tried setting up a new user in outlook. Also if they selected a group from the Outlook Address Book (OAB) non of the contact of the groups would display.
The item that resolved this error for me was:
In Exchange Management Console, Right Click “Organization Configuration”and select “Modify Configuration Domain Controller”… setting.
A new window will open. Browse for the proper info. Active directory will need to be working as well as some kind of name resolution (namely DNS) in order to select the domain and domain controller properly.
Once done hit OK. You will need to restart the services or restart the whole server. I restarted the services and that was all that I needed to do. Some people have had to do a full reboot of the exchange server after applying these settings.
This was done on a Microsoft Exchange Server 2007 running on Windows 2008 64bit.
