Outlook Security Alert for Someone Else's Certificate Problem
Posted on 2013-10-25
When I open Outlook 2013 on my Windows 8 Pro computer and open my Exchange 2010SP2 mailbox, I get a security alert for the domain "mail.company.com". The problem is that this is not a server in my domain. My server is "mail.northcompany.com". I select "No" to the alert and Outlook works flawlessly. The Exchange Connectivity Analyzer does not report any problems. I have tried deleting and recreating my Outlook profile, deleting/recreating/reinstalling server certificate, another version of Outlook, different computers with XP and 7, and connected to different networks with different ISPs and DNS servers. I don't get this message when I use OWA.
What is causing this alert and how to I get rid of it?
Thank you in advance!
(Note: I have replaced the actual server names with fakes that follow the same format for security purposes.)
