Journaling - Extraction Failures

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.

In some cases, although Mimecast can connect to the Journal mailbox and authenticate, the actual message extraction may fail due to a message blocking the queue.

Explanation

Once you have 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 the remote infrastructure, please consider the following:

• • • Does the Journal mailbox contain large items that might cause a time-out during extraction?
    • Does the Journal mailbox contain 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), please move them to a subfolder of the inbox and report this back to Mimecast support. Mimecast can then test extraction once more and hopefully continue extracting messages successfully.
