I have tried different mail clients but I am not able to send emails.
Thunderbird is giving me the below error :
Certificate Status: This site attempts to identify itself with invalid information.
Wrong Site: The certificate belongs to a different site, which could mean that someone is trying to impersonate this site.
Unknown Identity: The certificate is not trusted because it hasn’t been verified as issued by a trusted authority using a secure signature.
Outlook is also not working.
Please, can you help?
