SUMMARY

This article describes how to delete all the MAPI profiles defined for a Windows 95 or Windows NT user. This may be required in situations where a large number of profiles have been set up by MAPI applications that have not deleted the profiles after the applications have been uninstalled.

MORE INFORMATION

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

The location of the MAPI profiles varies, depending on the operating system being used.

For Windows 95, the profiles are saved in the registry under the following key: 
   HKEY_CURRENT_USER\SOFTWARE\MICROSOFT
   \WINDOWS MESSAGING SUBSYSTEM\PROFILES

NOTE: The text of the preceding command has been wrapped for readability. The break in the first line is not necessary when you type this command at your command prompt.

For Windows NT, the profiles are saved in the registry under the following key: 
   HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\WINDOWS NT
   \CURRENTVERSION\WINDOWS MESSAGING SUBSYSTEM\PROFILES

NOTE: The text of the preceding command has been wrapped for readability. The break in the first line is not necessary when you type this command at your command prompt.

To delete all MAPI profiles, delete the PROFILES registry subkey and recreate it.
