I just installed the latest production version (4.5.6) on RHEL5 and the pst import wizard is versioned the same. It won't import pst files from Outlook 2007. Elsewhere in this forum the question arises,"Are you using the latest version?". And, "It works with Outlook 2007 from version 4.7 or 5.0". But for the life of me, I can't find a reference to a link in the the forums or any of the Zimbra web pages. Am I just blind, or is this a secret?
