Hi I am working on an Outlook Application and Folder Management. I was working on an userid "XYZ" with the NT server. The id "XYZ" was removed accidentally and after that the services namely : 1. MS Exchange Event Service 2. MS Exchange Information Store Service 3. MS Exchange Message Transfer Agent (MTA) 4. MS Exchange Directory Services are not starting. XYZ has been given the administrator privileges in the Domain. The system reports the following error when trying to start the "MS Exchange Information Store" The Error reported is : "The Microsoft Exchange Information Store service terminated with service-specific error 4021." In the Event Viewer, it says that it cannot connect to the MS exchange Server Directory Service (Event ID being 1121) and cannot initialise MS Exchange Information Store (Event ID being 5000). Please let me know if any solution is available for this problem so that the services will start. Let me know details - Reg User Permissions - Reg the Startup Profiles that would solve this problem Regards Goutham
