Hallo. After at least one month of questions and answers with the support my problem (not possible to create new subfolders, not possible to move existing subfolders imported to ZD2 from ZD1) has not been solved.
I communicate for me it's impossible to use your software any more, as I use to create many folders and to archive mail inside them.
It's a pity, because I found Zimbra quite a good application. Nobody has been able to suggest me how to solve this stupid problem which seems not more than a permission / restriction one.
I don't really think the Zimbra support works, perhaps it does only with sold products, not with free ones.
