Hi Bob Shouldn't you be looking at the permissions on the individual Exchange mailboxes - you can find this in active directory if you look at advanced features
-----Original Message----- From: Bob ten Berge [mailto:[EMAIL PROTECTED]] Sent: 15 November 2001 12:12 To: MS-Exchange Admin Issues Subject: Security issue in Exchange 2000 Hi all, We got a strange problem here, this is what happens: When a normal user in our Exchange environment creates a new profile in his Outlook2000 client, his name and exchange server get underlined, meaning they are both validated; now when that person tries to add additional mailboxes to the profile, an error message pops up right away when clicking on the Add Mailbox button stating that the user cannot be found. Now we remove the profile from Outlook, I make that person a Domain Admin and he makes a new profile in Outlook 100% similar to the previous profile. But now when he hits the Add Mailbox everything works the way it should, i can even remove him from the Domain Admins group, it keeps working. When i make this person member of the group Administrators this does NOT work. So obviously we're dealing with a faulty security setting or police here. Ofcourse this solution is only temporary, on the Exchange2000 server something must be incorrect, I just don't know where to look anymore. I tried changing security settings on several objects within Exchange System Manager but i couldn't find anything there. Maybe i'm looking at the wrong picture here, but I was/am looking for some object that has different rights for Administrators and Domain Admins, if there is anybody out there that has a clue about what i am talking about, please help me!!
