Zimbra upgrade 5 to 6, no Briefcase, Documents

[Koffie]

Hi All,

We recently upgraded one of our older mail servers from ZCS 5 to 6 and it went very smoothly as expected.

However when I tried to update some of the users signatures to add an image, (which didn't work btw, pressing the insert image button does nothing) I realised there is no Briefcase or Documents tab.

Has anyone ever had this problem, I did a search and can't seem to find anyone who has had this problem.
