But before diving into the solutions for fixing this certificate-not-secure-for-email issue, let\u2019s first have a look at the reasons behind this error.<\/p>\n<h2>Causes Behind <strong>Outlook.com security certificate error or <\/strong>\u2018The Server You Are Connected to Is Using a Security Certificate That Cannot Be Verified\u2019 Error Message<\/h2>\n<p><strong>Wrong Hostname:<\/strong> The most common reason behind this error is that you have the wrong hostname configured in Microsoft Outlook. You might have mistakenly typed in the wrong hostname at the time of configuration.<\/p>\n<p><strong>Incorrect Port Numbers:<\/strong> Another obvious yet common reason is that you have the wrong port numbers entered in your mail server or in Outlook. This error might be caused due to this match in port numbers.<\/p>\n<p><strong>Incorrect Date &amp; Time Settings: <\/strong>This might sound too obvious or simple, but having incorrect date and time settings in your computer could be one of the prime reasons behind this unverified certificate error.<\/p>\n<p><strong>Blocked Ports:<\/strong> If some of the SSL ports used by Outlook are blocked, you won\u2019t be able to connect to the email account and it would result in an error practically shouting that your \u201cemail certificate is not secure.\u201d<\/p>\n<p><strong>Certificate Name Mismatch: <\/strong>A potential cause behind this error is having <a href=\"https:\/\/cheapsslsecurity.com\/blog\/brief-account-ssl-certificate-technical-errors\/\">different certificate names<\/a> in Outlook and your email server. Sometimes, ISPs change the names of their servers and this could cause this error.<\/p>\n<p><strong>Outlook Security Certificate Not Valid: <\/strong>This error generally means your Outlook security certificate has expired and is out-of-date. However, the good news is \u2013 you can procure a new certificate to keep your emails secure.<\/p>\n<h2>Methods to Resolve The \u2018Certificate Not Verified\u2019 Error<\/h2>\n<p><strong>Method 1: Correct Certificate Name Mismatch<\/strong><\/p>\n<p>The first thing you should try is checking the name of the certificate in Microsoft Outlook. Here are the steps to check and correct the certificate name:<\/p>\n<ol>\n<li>Click on the <strong>View Certificate<\/strong> button in the error dialogue box.<\/li>\n<li>Now, check the name in the Issued to Name section and to ensure that it has the same name as in the email server. If not, change it accordingly.<\/li>\n<\/ol>\n<p><strong>Method 2: Correct the Name and Ports of Your Domain<\/strong><\/p>\n<p>Many a time, having a simple name mismatch in the domain name causes Outlook to believe that the certificate isn\u2019t secure. Usually, this happens for one of two reasons \u2014 you have a subdomain as your domain, or you have your domain listed instead of the domain of your hosting company (in case of shared web hosting).<\/p>\n<p>Here are the steps to check and correct the name of your domain:<\/p>\n<ol>\n<li>Go to your email server configuration settings.<\/li>\n<li>Now, go to mail settings and find SSL\/TLS settings.<\/li>\n<li>Note the domains for incoming server and outgoing server. Also, be sure to note the IMAP, POP3, and SMTP ports listed.<\/li>\n<li>Open Outlook, go to <strong>Account Settings<\/strong> and double-click on the email ID that you wish to configure.<\/li>\n<li>You\u2019ll get a Change Account dialogue box. Change the incoming and outgoing domains to the domains you saw in your email configuration settings.<\/li>\n<li>Click on <strong>More Settings, <\/strong>click on the <strong>Advanced<\/strong> tab and check whether the ports match the ones listed in your email server configuration settings.<\/li>\n<li>Click <strong>OK<\/strong>.<\/li>\n<li>Click <strong>Next <\/strong>to finish the job and to check whether the error persists or not.<\/li>\n<\/ol>\n<div class=\"graysection\">\n<h2>Purchase an SSL Certificate &amp; Save Up to 86%!<\/h2>\n<p>We offer the best discount on all types of SSL\/TLS Certificates for your email server.
