Outlook connectivity to Exchange 2013 on .local domain
Posted on 2016-08-18
I need to reconnect Outlook to an Exchange Server that was in an internal .local domain. I recently changed from .local to .org internally and set up a new Exchange Server in the new domain. The old Exchange Server is in the .local domain. I have the old .local DNS server pointing to the old Exchange Server and the .local domain is isolated. I have one PC that is still a member of the .local domain. When trying to recreate an Outlook account, at the "Logging on to the mail server" stage, I get the message: "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action." The SSL Certificate might be the problem, because it is for the .org domain. I have read that a self-signed SSL cannot be used for Outlook. I also know I can no longer get an SSL with a .local fqdn. OWA will let me log on, but then returns a completely blank page, whether from the PC or on the server using localhost. I need to accomplish this to access the old Public Folders.
