Journaling - Errors

This article contains information on resolving Mimecast journal extraction issues, including handling large or envelope-less items in the journal mailbox and steps to report and test extraction with Mimecast Support.

Although Mimecast can connect to the journal mailbox and authenticate, occasionally the message extraction fails due to a message blocking the queue.

Explanation

Once you've confirmed that no infrastructure or device changes have been made, or if there are any known issues that may prevent the successful extraction of journal information between the Mimecast and remote infrastructure, consider if the journal mailbox contains:

• • • Large items that might cause a timeout during extraction.
    • Any items that do not hold a message envelope (when using Exchange Envelope Journaling).

Resolution

If you find messages that might be causing the issue (most likely the oldest items in the mailbox), move them to a subfolder of the Inbox and report this to Mimecast Support. Mimecast can test extraction and hopefully continue extracting messages successfully.
