But the inhouse Exchange server crashed and we moved to the cloud. was for our old Exchange server that was inhouse and local to me. I don't have access to the IIS log files, we have a vendor that host our Exchange on the cloud. I also have a "CNAME" called "autodiscovered_.com" How can I get rid of that old Exchange certificate alert from popping up without my old Exchange server? Unfortunately I can’t go back to my old Exchange Server.Įxchange 2010 Server (old server which crashed) They had to go back to their old Exchange server to prevent the old certificate from popping up. I read a post where someone had this same Security Alert issue because they didn’t decommission their old Exchange server correctly.

We think they Lync Certificate control panel pushed that old Exchange certificate somehow.

What changed you ask about three days ago? Well, we have a Lync 2010 server we are trying to implement and it requires a certificate. I tell the users to click “No” to the alert but the alert keeps popping up every time they reopen Outlook. Only a couple people reported it but now it’s spreading. This issue started happening about three days ago. First I thought it had something to do with the users old Outlook profile before the crash, but we have one new user getting that Security Alert even though he has a new computer and Outlook was freshly installed Our Outlook 2010 are configured using Outlook Anywhere to point to the cloud but for some reason some Outlook users are getting that Security Alert trying to get the user to accept or deny the That Exchange server crashed back at Sept. The name of the certificate is from my old Exchange 2010 server. I am getting a Security Alert from a security certificate while opening Outlook.
