Our environment is currently EV 9 SP2.  At some point in the last weeks or so, enterprise vault stopped automatically enabling mailboxes for EV.  The event log gives the following error for every new user that it tries to enable.  Manually trying to enable a mailbox gives the same error and result.  Existing users continue to work fine.  I can't find anything that has changed that anyone is aware of.

Event ID: 3139 An non-specific error has occurred whilst enabling archiving for the mailbox <MailboxName> Error: <0x80040115> 

I verified that the vault service account is ok and the mailbox for the exchange server can create profiles in outlook on the server.  I tried a dtrace on the Agent Client Broker and pulled a small section of the log below where the error occurred.  I'm not sure what my next steps should be to track down the cause of this.  ClosestGC registry key is already set.  I've looked at things per other forum posts like homeMTA and they look ok as well.  Any help or directly would be greatly appreciated.  Thanks!
