Hi: Exchange 2000 Enterprise edition on windows 2000 member server. 1. When i create new user and it gives me the option to Create an Exchange mailbox, but when i go to Server->Mailbox Store->Mailboxes...there is no mailbox for the new user. 2. When i create mailbox for Existing AD users, it doesnt create them either. 3. When i try to create Exchange Address List I got this error: Exchange System Manager Access Denied Facility: Win32 ID no: 80070005 Exchange System Manager. Any Idea. Thanks in Advance. Rajiv
