When I attempt to add a Universal Distribution Group (UDGs) to a client permission of public folder,it show the error 80004005
I seek the information in MS web I find that it said that
the Exchange information store converts the UDG to a USG. Only a Native-mode Windows 2000 domain can make this conversion, because USGs are only available in Native mode. If a Mixed mode domain attempts the conversion, you receive the error messages that appear in the "Symptoms" section of this article.
I have a question, Need all server of windows 2000 to be native mode or only exchange servers to be native mode?
