Outlook Security Certificate Message
Hello Experts
We are getting the attached certificate error in Outlook. We can click on "yes" and Outlook works fine. I have tried installing the certificate but message comes back next time Outlook is closed/reopened. It seems the certificate is from cPanel and is expired. Not sure who cPanel is and how to get an updated certificate. See attached certificate info.
We are using Exchange Online (Plan 1) from Microsoft with Outlook 2010/2013 on desktops,
We have 4 users that are using Office 365 Premium with Outlook 2016 and they do not get the error.
I'm also getting event ID 36886 on one of the 2012 domain controllers, not sure if this is related.
Event Type: Warning
Event Source: Schannel
Event Category: None
Event ID: 36886
Date: 3/20/2018
Time: 7:22:12 AM
User: NT AUTHORITY\SYSTEM
Computer: servername.domainname.coma
Description:
No suitable default server credential exists on this system. This will prevent server applications that expect to make use of the system default credentials from accepting SSL connections. An example of such an application is the directory server. Applications that manage their own credentials, such as the internet information server, are not affected by this.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
Any help is appreciated.

The suggested solution was for event ID 36886.
To resolve the Outlook security certificate message, I removed an old pop3 and smtp server ip from internal and external DNS servers.
