• View MAPI stores hierarchy. Enables browsing through all available MAPI stores within an Outlook or Exchange profile. Displays the complete folder structure, messages, and associated objects, allowing navigation through the underlying messaging system data.
• Edit MAPI properties. Provides ability to modify MAPI properties in multiple formats including ASCII, Unicode, RTF, or binary streams. Users can change values, add custom properties, or delete existing ones to test client email behavior.
• Calculate store checksum. Computes and verifies data integrity within a MAPI store. Helps detect corruption or inconsistencies by comparing checksums across different store states.
• Convert between MSG and EML. Uses the IConverterSession interface to transform Outlook MSG files to standard EML format and vice versa. Useful for migrating messages between systems or debugging email content.
• Apply content restrictions. Creates and applies filters on folder or message tables. Restrictions can be based on specific properties such as subject, sender, or dates, limiting displayed results during inspection.
• Dump store content to text files. Exports complete store or server content to plain text files. Facilitates forensic analysis or external documentation of MAPI structures without relying on the graphical interface.
• Compare entry identifiers. Compares two MAPI EntryIDs to determine if they reference the same object or store. Helps resolve duplication issues or incorrect references within the Exchange profile.
• Activate table notifications. Subscribes and receives real-time notifications about changes in MAPI tables, such as row addition, deletion, or modification. Useful for monitoring dynamic events in mailboxes or public folders.
• Encode EntryIDs for MAPI protocol URLs. Transforms entry identifiers into encoded strings usable in MAPI over HTTP protocols. Necessary for debugging direct links to objects within Exchange infrastructure.
• Open objects as EntryID or direct object. Offers two methods to open MAPI items: via entry identifier or via direct object reference. Allows testing different access paths and evaluating permissions or visibility.
• Set default store. Designates which MAPI store is considered default within the current session. Useful for simulating client behaviors where the primary mailbox changes temporarily.
• View address book hierarchy. Displays the complete structure of containers, lists, and users within the MAPI address book. Helps verify replication and existence of directory objects.

The development history of MFCMAPI began around the year 2006, created by Stephen Griffin and other Microsoft engineers. The program is written primarily in C++ using the Microsoft Foundation Classes (MFC) platform. Its original purpose was to provide an internal debugging tool for the Exchange and Outlook teams, and later it was published as a reference sample for developers working with the MAPI API. The official repository is hosted on GitHub under the Microsoft organization, and multiple developers have contributed over the years, maintaining it as a technical reference for advanced messaging diagnostics.
