Developer Tools

Last reviewed on December 30, 2013

This is a collection of tools used to view inside MAPI message stores, including Exchange mailboxes and PSTs. Two of the tools, MFCMapi and MDBVu32 are provided by Microsoft.

While these tools are designed for developers, they can be used by anyone with basic knowledge to browse for and delete hidden items in a mailbox or PST. Should you need to use these tools, always make a backup of your PST or mailbox first. If you delete messages or other items in error using these tools, you cannot recover them unless you have a backup.

Redemption provides a hook into Extended MAPI which developers can use to create add-ins that avoid security alerts. Outlookcode.com has more information on using Redemption.

See Outlook Developer Resources for more resources.
