We have 2 other PCs set up with RPC over HTTP running Outlook 2007, which are working fine. However, there is one that keeps getting the error "The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action." when the username and password are entered.
I followed the same steps I did on the other 2 PCs that are working fine. There is no encryption.
Thank you for your help.
