Messages Stuck in Submission Queue Exchange 2010

There’s an issue that appears to pop up periodically with Exchange Journaling, is due to having a BES server attached to your Exchange environment or if a user has a broken signature in the Outlook client. It appears some or all of these messages are calendaring responses with a subject like “Accepted: Meeting Name” or “Declined: Meeting Name”


Messages get stuck in “Retry” in the Submission queue, which shows as an Event 9213 in the Application log:


Log Name:     Application

Source:       MSExchangeTransport

Date:         1/21/2016 1:28:06 PM

Event ID:     9213

Task Category: Categorizer

Level:         Error

Keywords:     Classic

User:         N/A

Computer:     <Servername>


A non-expirable message with the Internal Message ID 78717083 could not be categorized. This message may be a journal report or other system message. The message will remain in the queue until administrative action is taken to resolve the error. Other messages may also have encountered this error. To further diagnose the error, use the Queue Viewer or the Exchange Mail Flow Troubleshooter.

Looking at the message info as shown below:



The server responded with: 550 5.6.0…… This appears to be the local Exchange server, not the destination server. This message can be removed from queue using the below command:



Get-Message -server <Servername> -filter {FromAddress -eq “<>” -and Status -eq ‘Retry’} | Remove-Message




Great if you go back to “Queue Viewer” and check the messages are Removed.




Update: This appears to be a documented bug in KB2381250. However, the KB Notes that it should be patched as of SP2 RU3 and it still appears to be an issue in SP3.


Further update: Looks like this is a distinct bug from the reported in the above KB. Scheduled to be patched in SP3 RU3. Specifically, my issue seems to deal mostly with meeting invite replies (Accepted/Declined, etc.)
