There are some users said there Zimbra Destop can not sync the sent folder.
It means when they compose one email, they can't check it in sent folder.

when I check for them, I found the stats of Zimbra is offline and can not see any update except inbox. When I try to debug it. It shows me the following information:

java.lang. RuntimeException: missing meta entry reading tgz stream

So anybody has idea on that?
