I have an Exchange Server 2013 and I am trying to connect using Outlook 2010. Both are running on the same server. The Outlook installation is just for testing mailboxes.
Outlook first refused to connect because the network adapter didn't have a default gateway and apparently Outlook requires a default gateway to connect to 127.0.0.1.
Now the network adapter has a default gateway and Outlook continues to pretend that it cannot find the Exchange server.
The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
This happens regardless of whether I use the Exchange server's name ("exchange") or its (fixed) IP address or "localhost" or 127.0.0.1.
What am I doing wrong?
After that error message, this small window appears with a slightly different error message.
For some reason Outlook cannot "resolve" the name 127.0.0.1. The same message appears when I try any other name or IP address that points to this same local server including localhost and the server's name and the server's IP address in 192.168.0.0/24.
