I was able to link straight to a message but only in the Standard Version interface. Actually, that's how I found out how to do it. If you click on the Standard Version button up top and then click on any message it shows a URL similiar to this:
http://mailserver/zimbra/h/search?si...w&id=NNN&xim=1
(NNN is the message ID number)
Since we lose a lot of functionality in the Standard Version I am still trying to link to messages in their Advanced Version interface. We have a channel in our portal that shows the user's inbox and we would like to take the user directly to the message when they click on it in the channel instead of taking them to the Zimbra interface and making them click (once again) on the message they wanted to see.
If anyone find a solution, please post. I find it strange that they allow you to open messages in this manner but only in the Standard Version. Maybe the Advanced Version is not all that advanced.
