We have installed Zimbra 6 Network Edition a few month ago for hosting email of our customers. It works well, but the document management Web function is quite limited. Moreover the webdav standard seems to not be fully supported (ie the locking function)

Do you have information of future updates that could provide document locking functions for instance?
Because this function is really mandated for some of our customers.

Another cool feature is the direct edition of MS Office documents with IE and Windows as provided by Sharepoint.

Thanks for responses..
