Certificate Error
Couple of my users are receiving this error for outlook.office365.com in Outlook 2010. Any ideas?

This is common erorr if you do not have the SSL certificate by compelete FQDN of destined client domain/server. Example: server1.contoso.com.
Try fixing the name of the certificates in your environment/office365 connection. Infact you have to improt new certificate from CA authority server in your environment.
Hope this helps you to fix the issue at your IT environement.

Why would I need a SSL certificate when I'm connecting to outlook.office365.com?
Our Autodiscover CNAME entry for our domain points to autodiscover.office365.com. All of our mailboxes are in Office365, none are on-prem.
