The auto accept agent no longer responds to requests.  I have tried re-registering the mailboxes, uninstalled/reinstalled the agent, etc but still no response.
Watch Question

I configured the Auto Accept Agent on Exchange 2003 back in 2007 using Microsoft TechNet article - http://technet.microsoft.com/en-us/library/aa997184.aspx.

Have you verifies the mailbox registration?  See http://technet.microsoft.com/en-us/library/bb124104(EXCHG.65).aspx.


Yes.  If I try to re-register the mailboxes I recieve a message stating "Event binding already exists".  However, if I run the MailboxStatus.vbs script I see all mailboxes return a status of "2 - Registration status cannot be determined."
Do any of the mailboxes contain invalid characters?  I had an issue with a mailbox that contained '&'.


No special characters.  These had been working for years but I started hearing about issues back in November.
I assume there is only one Exchange server?  Are there any related errors in the Application event log.


There is one additional Exchange server in a remote office and there are no errors logged in the event viewer.
Do the registered mailboxes in question reside on both Exchange servers or only one?


Only one.  There is no mailbox agent installed or registered mailboxes on the other Exchange server.
Verify that Auto Accept Agent is registered as a COM+ component
1. Start Component Services.
2. Expand Console Root, Component Services, Computers, My Computer, and then click COM+ Applications.
3. In the details pane, verify that Auto Accept Agent is present. If Auto Accept Agent was installed to run as Local System, it will also appear in the Services snap-in.


The agent is registered and running as a System Account - Local System.  It also appears in the Services snap-in.
Have you tried removing the binding (per http://technet.microsoft.com/en-us/library/aa997282(EXCHG.65).aspx) and re-registering the mailboxes?


I have removed/re-registered the binding successfully.  However, there is no change to the status (MailboxStatus.vbs still returns "2- Registration status cannot be determined".  I also tested unsuccessfully one the mailboxes.


Still looking for assistance....anyone?


still needing assistance....
Root issue was that the system mailbox was missing from all mailbox stores.  The stores were dismounted and new databases created for each, which re-created the system mailbox for each store.  Once the mailboxes were re-created the mailbox stores were reattched to the original database files.  Stores were brought online.  Each mailbox needing to have the autoaceept agent sink was registered and the auto accept agent is now working flawlessly.  Interestingly, the time that the mailboxes disappeared coincides with the time that EMC's EmailXtender was installed against our Exchange environment.
