Each member of the post office has a personal database (userxxx.db) that represents the user’s mailbox. The user database contains the following:
Message header information
Pointers to messages
Personal address books
When a member of another post office shares a folder with one or more members of the local post office, a “prime user” database (puxxxxx.db) is created to store the shared information. The prime user is the owner of the shared information.
Local user databases and prime user databases are stored in the ofuser directory in the post office.
Because resources are addressable just like users, resources also have user databases.
For the location of user databases in the post office, see GroupWise 2012 Troubleshooting 3: Message Flow and Directory Structure. For more post office information, see Section 35.3, Information Stored in the Post Office.
