You may have tried at least once to log in to your email and encountered an email certificate error, but didn’t know how to work around it.
Certificate errors happen whenever there’s an issue with a certificate or a web server’s use of the certificate itself, thus Internet Explorer, Edge, Chrome, and other browsers display red flags through warnings about certificate errors.
The most common reason is that the certificate is valid for a certain period of time, so if your computer’s date and/or time is set to a different date or time, then you are likely to get the email certificate error warning.
However, if you still get the email certificate error even after adjusting the date and time, then it is possible that either the certificate of the website itself has expired and needs to be renewed, or, the website is not to be trusted.
You could have encountered the email certificate error on a site you visit regularly without errors, so in this case, the website itself may not be configured correctly.
Another cause could be that the website’s certificate has expired and the owner or operator needs to renew it so that you continue using it, as this cannot be corrected in your browser.
When you get an email certificate error, it is advisable that you do not put important login identities or passwords on such pages.

Check to ensure your time and date on the computer are set to the appropriate or correct values. If you set ahead of or behind the actual time/date, the certificate can read as invalid.

2. Try out a more powerful email client

4. Configure the use of mail over SSL settings
If you’re trying to connect to your email using a default mail server name, what happens is there’s a mismatch between the domain name, and that of the shared SSL certificate on the server, which results in an email certificate error.
In order to remove the email certificate error you receive, configure your email client with an SSL setting, because by default, when sending or receiving emails, they’re not encrypted so if they’re vulnerable and easy to intercept by cybercriminals.
Some users opt to use email over SSL owing to restrictions by their Internet service provider that prevents them from sending any email messages.
In order to use your email over an SSL, update the settings for both incoming and outgoing servers, plus ensure your email client has port 465 configured as the SMTP port.
