shared tags or other kind of "marks"
is it possible to share a Tag with other Zimbra accounts? I've read the end-user documentation and seems not :(
My goal is: given a shared folder accessible to many users, I would like to "flag/tag/mark/..." a message in this folder in order to let other users know that this message has been treated for some stuff by someone else. Of couse I do not want to use the already-available "red flag", or I could use this with another color at least.
Any suggestion on how to achieve it?
