All of a sudden I am unable to modify "mailbox rights" via the AD MMC without having to access the exchange server ESM directly. Apparently there is some connection with my XP AD MMC and exchange system that is causing the error but I have no clue where to start.
Here is the complete error message:
The action could not be completed because the Microsoft Exchange Information Store Service is unavailable. Be sure the service is running and you have connectivity to the Microsoft Exchange Server computer. ID no: c1041721 Microsoft Active Directory - Exchange Extension
I am running WinXP SP2, MMC 3.0 and Exchange Server 2003.
