Hi, please see if anything here helps - "This Connection is Untrusted" error message appears - What to do.

If your question is resolved by this or another answer, please take a minute to let us know. Thank you.

I don't understand why a site as common as gmail and google search haven't been tested for this before the release.

I have users who are not very tech savvy and work from remote locations and I cannot send them highly technical solutions.

Hi, your problem is nothing like as commonplace as you seem to think. If it was, we would be seeing thousands of users complaining about the same thing - which we aren't.

It could be as simple as having the wrong date set on your users machines, so please try working through the linked article. If that doesn't help, telling us the exact error message as shown in the article will help us to provide a solution.
