Hi All, I am new to exchange server, I have been trying to install and configure exchage as a project were we may have to shift to exhange in the near future. All has come out well for me from the installation part to the end of configuring the clients machines. I feel great that I have done it. and it is working fantastic. I also thank the exchange list for my success. I have been learning a lot. One query? 1. As an exchange administrator. I should be able to open others mailboxes. How should I go about it, If I want to open the mail box of another user? (Lets say that I do not know the password of the user. but I have logged in as an administrator.) Thank you once again. Regards Balaji Naidu Systems Administrator
