Journaling - POP3 SVC Error

This article contains information on resolving the POP3SVC error 1023 with code 0x7da in Exchange, which occurs when the POP server fails to render messages properly. It provides steps to isolate and move problematic messages to prevent retrieval issues.

Journaling generates errors on the Exchange server.

Explanation

The error 1023 with 0x7da in the Windows Application Event Log means that we are trying to retrieve a message from the Journaling mailbox, but the POP Server fails to render the message properly.

Log Name : Application
Type : Error
Date/Time: Day, Month Date, Year at Time
Source : POP3SVC Category : Content Engine ID : 1023
UserName : Desc : Error 0x7da occurred while rendering message

Investigation in the past has shown that typically this indicates there is something wrong with the structure of such messages, and the POP Server doesn't allow Mimecast to retrieve them properly. When you place them in a subfolder of the Inbox, we will not try to retrieve them, but they will be there for future reference.

Resolution

1. Log in to the Journaling mailbox using OWA or an IMAP Client.
2. Sort the items by date.
3. You will most likely find a message that is relatively old compared to the other messages.
4. Please create a subfolder under the Inbox and move this 'older' item to the subfolder.
