I recently started using Zimbra and Zimbra Desktop. Enjoying a great product!
However not every is running smooth, but hey it is my choice to install on 64 bit Ubuntu and mess up settings :-)
To solve some of the issues I had I started searching for these support forums. First to find them offline at zimbra.com/forums and still being offline there today. I got there by clicking on "forums" in the menu of wiki.zimbra.com
Suggestion for improvement: Change the menu link to the forums on the wiki pages.
DuckDuckGo led me to this place in the end. So I hope I'll get some tips as to how undo my messing up things. However after clicking on the Zimbra logo in the header I was led to the community homepage. No problem, there is a support link that takes you to a page with a link to the support forums. Unfortunately though that page does not list all forums.
Suggestion for improvement: Display all available forums on this page: [View:https://community.zimbra.com/support/f:940:0]
