Google Apps Vault saves emails in mbox files. Unlike Google Takeout, message status information (unread, deleted, etc.) is not stored in the mbox file. This information is stored in a separate XML file that has a name ending with “-metadata.xml”.
Before processing mbox files from Google Apps Vault, make sure you place the corresponding “-metadata.xml” file in the same folder. If the corresponding XML file is missing, Aid4Mail won't recover message status information.
Aid4Mail can also determine the source folder names (or Gmail labels) based on the information in the XML file. In some cases, an email message may belong under more than one folder. Unfortunately, Aid4Mail is currently designed to export an email to a single folder. As a result, if a Gmail message has more than one target location assigned to it, Aid4Mail will choose the target folder in the following order:
2. Sent Mail
6. User Defined Label (first one listed if more than one)
7. All Mail
Note that the Google Apps Vault option is not available in Aid4Mail Home.
