We were locked out of our old router. I got a new router, changed it's IP address and the starting DHCP pool to approximate to the previous router, and installed.
Client computers can connect to the servers SQL database fine, but when trying to connect or add the old exchange mailbox the following error comes up.
"The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
So I am in Exchange System Manager - what do i look for?
Here is another issue.....before I changed the routers IP address to be the same as the old router, the server would not even connect to the internet. It seemed to be blocked somehow - is that related?
