Windows Mail App Password Recovery

System Requirements

This tool works with the built-in mail application of Windows 10 and Windows 11. Both 32-bit and 64-bit systems are supported.
You can also use this tool on older versions of Windows (like Windows 7) for recovering data from external disk with Windows 10 or Windows 11.
Be aware that WinMailPassRec can only recover the passwords of POP3/IMAP/SMTP/Exchange accounts. It cannot recover the passwords for other types of accounts like Microsoft account or Gmail.

Version History

  • Version 1.01:
    • Fixed a problem with decrypting Windows Mail passwords from external drive on Windows 11 22H2.
  • Version 1.00 - First release.

General Information

The mail App of Windows 10 and Windows 11 stores the POP3/IMAP/SMTP/Exchange accounts information in 2 different places:
  1. Under the following Registry key: HKEY_CURRENT_USER\Software\Microsoft\ActiveSync\Partners (Every account on different subkey) - Most of the account information is stored under this Registry key, but without the server and password information.
  2. The passwords and server information are encrypted and stored inside Windows Vault (Located under the following folder: %LocalAppData%\Microsoft\Vault\4BF4C442-9B8A-41A0-B380-DD4A704DDB28 )

WinMailPassRec combines the information from the above 2 places.

Start Using WinMailPassRec

WinMailPassRec doesn't require any installation process or additional DLL files. In order to start using it, simply run the executable file - WinMailPassRec.exe
After running WinMailPassRec, the 'Advanced Options' window is opened, and then you can choose to load the Windows Mail accounts from your current user, or from external hard drive plugged to your computer. If you choose to load the Windows Mail accounts from external disk, you have to fill more fields in order to decrypt the mail passwords.
After choosing the desired option, click the 'OK' button, and WinMailPassRec will display your Windows Mail accounts in the main window. You can select one or more mail accounts (or press Ctrl+A to select all) and then export the list to comma-delimited/tab-delimited/HTML/XML/JSON file by using the 'Save Selected Items' option (Ctrl+S). You can also copy the email accounts list to the clipboard (Ctrl+C) and then paste them to Excel or other application.

View Windows Mail accounts on external drive

If you want to recover the passwords and other details of Windows Mail accounts stored on external disk plugged to your computer, choose 'External Disk' in the 'Load From' combo-box of the 'Advanced Options' window, and then fill the other fields: The login password of the user, Protect folder of the user profile (e.g: G:\Users\user10\AppData\Roaming\Microsoft\Protect ), Vault folder of the user profile (e.g: G:\Users\user10\AppData\Local\Microsoft\Vault ), and the Registry file of the user profile (e.g: G:\Users\user10\ntuser.dat ).
Be aware that if Microsoft account was used to login, you have to extract the actual decryption password with the MadPassExt tool and then paste this password into the login password field.

You may also need to run this tool as Administrator (Ctrl+F11) in order to allow it to read the files from the user profile. If WinMailPassRec cannot read the files, error message will be displayed in the bottom status bar.
