    Office Outlook Security Certificate Out of Date.


    I keep getting the attached Security Certificate warning on my computer when I open Office Outlook. I have updated the certificate but it hasn't made any difference. How do I get rid of this Security Certificate problem please? Please note I am not using Office 365. I have Office 2016 on my computer. When the certificate warning appears I usually get a request to sign into my email at Microsoft Outlook.com. Any thoughts please?

  2. Outlook closes after asking about security certificate


    I have most recent version of Outlook for Windows Ten with six e-mail accounts. It has operated without a problem since installation -- about two weeks ago. It has always asked me if I will accept the security certificate from one of my e-mail providers. Whether or not I accept, I have always been able to continue with my other accounts. Now, however, it asks asks me to accept the security certificate, but Outlook closes immediately, whether or not I accept the security certificate.

    security certificate

    Hi,

    Thank you for posting your query on Microsoft Community.

    I would like to know if this issue occur on Different Web browsers too?

    I would suggest you to try the following steps, when you access secured website you may get this error message.

    1. Open Internet Explorer and verify that the page you are trying to view is listing a certificate error.

    2. To clear the certificate error goes to Tools --> Internet Options from the menu of IE 11.

    3. Click on the advanced tab and scroll down to the security section. Clear the boxes for: "Check for publisher's certificate revocation" and "Check for server certificate revocation".

    4. Click Apply and Ok.

    5. Attempt to reload the page by clicking the Refresh button at the end of the address bar or by pressing the F5 key. Your page should now load as expected.

    This error can be cause by the SSL certificate of the website – maybe it was not issued by a trusted Certification Authority on the client side. It could even be an attempt to fool you or intercept data you send to the server. Or maybe the certificate has
    expired.

    I suggest you to refer to the Microsoft help article and check if it helps.

    https://support.microsoft.com/en-us/kb/931850

    I would suggest you to refer the link below and check if it helps:
