Can't Send Emails--stays in Outbox
I just downloaded Zimbra Desktop, I'm using Windows 7 (64-bit). I created a test email message and clicked "send" and the message is now sitting in the Outbox. I cannot figure out how to get it from the Outbox to be actually sent to recipient. I am trying to replace using Microsoft Outlook (my system has a trial of Microsoft Outlook 2007 which has expired, which means the send function is disabled in Outlook).
Can I get Zimbra to send this email, and how do I do that?
