XFOR: Exchange Dir-Sync Failing with Event ID 134 (159295)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q159295 SYMPTOMS
After you apply Microsoft Exchange Server Service Pack 3, directory
synchronization (dir-sync) between Microsoft Exchange Server and Microsoft
Mail fails. After you turn up diagnostic logging on the Microsoft
Exchange directory synchronization agent (DXA), the following event ID
appears in the application event log:
Event ID: 134
Type: Error
Source: MSExchangeDX
Category: Event Handler
Description:
Error MH_RC_SESSION_BUSY returned by the MTA. (Thread 812).
CAUSE
Copying the Microsoft Mail Administrator mailbox on outgoing (from
Microsoft Exchange Server) dir-sync messages (whether the computer running
Microsoft Exchange Server is a dir-sync server or requestor) and then
deleting these messages from both the Inbox and Deleted Items folder
without reading them causes a non-read notification (NRN) to be returned
to the Message Transfer Agent (MTA). The MTA fails during message
conversion (MDBEF -> P2) and the message is incorrectly handled.
WORKAROUND
To prevent this problem, do the following:
- Don't copy the dir-sync administrator on dir-sync messages.
- Don't delete the dir-sync messages.
- Open the messages before deleting them.
RESOLUTION
Apply the fix referenced below. The MTA code was fixed to properly handle
the message conversion.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange version
4.0.
This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
