I want to add an account in outlook 365.

 

However, an error message was prompted saying that my security certificate was expired.

 

What should I do?

I would suggest that you try to use the tool here in setting up your account:

https://support.office.com/en-us/article/About-the-Microsoft-Support-and-Recovery-Assistant-e90bb691...

 

Might be helpful if you take a screenshot of the error message and post it here. Another thing is if your email address domain is used as a website as well, verify if the certificate of the website is still valid.

In addition to what was suggested above, also try and disable any firewall/antivirus on your network. Then check the behavior
