I am using internet explorer 11 and when I try to go to my site I get a certificate error. I sat on the phone with Microsoft for an hour. I down graded my internet explore back to 10 and I can open the site with out any problems. But what about my guests? I don`t expect any of them to go threw all of that. Or enter a site that if flagged as malicious. How do I fix this my invites just got sent out.
