Sounds like some administrative issues are possible such as changes to rights, GPO's, etc.
However, to start to rule things out, how about gathering dcdiag and netdiag reports for the GC's and the Exchange servers? To run dcdiag from a member server, you specify the DC you want it to collect. Also, what kind of topology are you using? W2k3 FFL? Mixed? Who has administrative access to change rights? I see three separate (possibly related, but separate issues anyway) issues: 1) wide-open rights are available to all users 2) missing mailboxes 3) unable to create new users To unravel all of that, it's necessary to know if this is native mode domains, native mode Exchange, Forest functional level, topology of the deployment (AD and Exchange) and which servers hold the AD and Exchange roles. Installed software on the DC's and Exchange servers would be a helpful item to know as well.

Up until now, it was "secure" in that people had to assign delegates, but now it's pretty much wide open. Additionally, the Private Information Store shows *none* of the user logons or mailboxes. Two user mailboxes won't open ("Cannot be found / Does not exist" errors opening with Outlook). But ...... all other users can open their mailboxes, send & receive mail, use the global address book, and do pretty much anything they normally do with e-mail. From Active Directory Users & Computers, we cannot add email accounts, nor can we make changes to existing users' Mailbox Rights from the Exchange Advanced tab within User Properties. Clicking the Mailbox Right button returns "There is no such object on the server. Facility: Win32 ID no: c0072030 Microsoft Active Directory - Exchange Extension. As it stands, we're thinking there's little time left before this self-destructs. Things came to a halt yesterday afternoon, and after several hours of getting no answers from Microsoft, our Network Admin found that the Exchange Connector in AD Sites & Services wasn't working, deleted & re-created it, then restarted the three Global Catalog Servers, which got mail back up and limping along. Any ideas? Monte Barnett Network Specialist Burlington-Edison School District 491 N.
