I have a connection problem with Outlook 2007/2003 and Zimbra 7.

Zimbra works fine, but I try to qunado crare an email account in Outlook I get the error that the certificate has not been verified.

I get the error with outlook 2003 and I can not do anything.
with outlook 2007 I can say I still use the certificate.

how to solve the problem?

I get this error if I use both, or imapSSL imapNOssl
