I am using Windows 8 Pro x64 with Zimbra 7.2.2.
I also have domain and mailbox on it.
When I'm trying to add this account to Zimbra, it says, that there is self-signed certificate, and it will be not trusted.
I am unable to accept this certificate, and because of this, unable to fetch mail.
Works fine on Thunderbird.

How to accept this certificate or add domain to whitelist/trusted?
