I've been using Zimbra Desktop as an excellent backup to Outlook and was using it with IMAP Godaddy e-mail. However, I just switched my e-mail over to a Microsoft Exchange Server. I can't seem to get Zimbra to connect now and keep getting SMTP outgoing server error messages.

The incoming server is mail.ex2.secureserver.net, port no. 993; the outgoing port given to me from GoDaddy is smtp.ex2.secureserver.net, port no. 465.

GoDaddy publication suggests that TLS rather than SSL is needed.

Does anyone have any recommendations? Thanks.
