Certificate Errors

Older Macintosh computers with an outdated Apple Mail may not handle SSL correctly. If you are getting a Certificate warning for a known good Certificate each time you access your mail, you may need to disable SSL to stop the warnings. Disabling TLS/SSL will stop encrypting mail sent between the mail server and your Mac and instead send the mail in plain text. For an immediate fix, select Continue and you’ll successfully access your mail. OlympusNet does not recommend disabling TLS/SSL which exposes email in plain text.
