I have a strange problem: In the AD I have made groups and sub groups where the users are structured, in the standard "user" folder there are severeal users also that we use as test users to thecompanies produkt. In the standard user folder i can't access themailbox rights under the advance Exchange tab. The error reads: The action could not be compleated because the Microsoft Exchange Information Store is unavailable. Be sure the service is running and you have network connectivity to the Exchange Server Computer. ID no.:c1041721 Microsoft Active Directory - Exchange Extension I dont have that problems in the Sub groups. Anyone have any ideas? Thx in advance.

I realize that your post is almost a year old and was never answered but...did you or anyone ever solve this problem? Thanks
