All of my outlook users are getting a server certificate warning.
We have a mix of outlook clients that include outlook 2002, 2003, and 2007.
We are not using the outlook connector but are accessing the Zimbra mail server via pop3 with ssl for incoming on port 995. When the users open outlook they are getting this warning
"The server you are connecting to is using a security certificate that could not be verified. A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. Do you wish to continue using this server? Yes No"
I have added the server to the trusted sites in the Internet Options (Intranet) but did not solve. I have been reading a lot of stuff from the web but it all has to do with Exchange and Outlook. The certificate has not expired and was created from the SUSE/Zimbra mail server in our local domain. Can someone please help me figure out how to stop this pop up. It is not causing any problems with users receiving their mail as long as they click yes. It is just an annoyance.
This was not a problem for our Thunderbird users, we just select accept always and it went away. I wish all my users would use Thunderbird.
