Prompt When Sending Email

[bigmck]

The past three or four days I have been getting this prompt when sending an email on my Outlook 2013.
It says my Certificate on my Outbound Server has expired. I don't always get the Prompt, just about half the time. It gives me the option to renew it but the strange thing is that the Prompt refers to a Yahoo Server and the one in my Outlook is Att.net. Should I renew this certificate or does it sound like a Virus waiting to infect? Thanks,

Hi,

It doesn't look like it is malicious, the certificate (cert) is just probably outdated because of updates to the cert. This should offer some insight: Cannot verify Security Certificate warning - MSOutlook.info

My first thought would be to delete the cert, see at bottom: Import, export, or remove a certificate for a contact Then pick an email that you know throws this warning, your email should go through and update the cert for it. Otherwise you may have to follow the directions in the first link to update the cert manually.
