I use Outlook classic as my email client (I am physically disabled and use speech recognition and Outlook classic works well with this software).</P> <P>For the past few weeks, the 1st time I try to send an email, I received the following error:-<BR />the server you are connected to is using a security certificate that cannot be verified</P> <P>The target principle name is incorrect.</P> <P>Do you want to continue using the server?</P> <P>Now if I click yes, the email send successfully. However is there anyway I can fix this?</P> <P>Thanks</P> Wed, 03 Dec 2025 20:27:21 GMT https://community.plus.net/t5/Email/Security-certificate-error/m-p/2030924#M55898 wheels496 2025-12-03T20:27:21Z https://community.plus.net/t5/Email/Security-certificate-error/m-p/2030927#M55901 <P>This is probably down to Outlook and its "I know what I am doing" self configuration of the outbound server.</P> <P>Plusnet's outbound server is not smtp.something - it is relay.something depending on the brand.&nbsp; Correct the server name and the certificate issue will be rectified.</P> Wed, 03 Dec 2025 21:05:44 GMT https://community.plus.net/t5/Email/Security-certificate-error/m-p/2030927#M55901 Townman 2025-12-03T21:05:44Z
