After upgrading to Outlook connector 5.0.15_GA_2850 and applying the new Outlook hotfixes Outlook 2007 improvements in the February 2009 cumulative update - Zimbra :: Wiki
all sent items are from "Unknown", instead of my own name...
Did this happend to anyone else? All my users are reporting this problem...
What's odd is that messages sent from the PDA are reporting the send correctly, so this must be an Outlook-related issue.
Server is 5.0.15_GA_2850.
