Zimbra as Default Mail Client

[pcOxygen]

I have Zimbra Desktop installed and would like to set it as my DEFAULT Mail Client in Windows 7. Clicking on the Start menu, and then Default Programs, Zimbra is not listed.

How can this be accomplished?

There's a checkbox in the Prefs->Other section labelled "Use Zimbra Desktop as default mail application".

It works under XP. To unset ZD as the default you'll have to use the Internet Options Control Panel or IE Internet Options to set another client as default.
