SYMPTOMS
If the User-Level Access Control option is enabled when you attempt to share a folder in Windows, you may receive the following error message when you click Add to add user-level permissions:
CAUSE
This behavior can occur for either of the following reasons:
- Outlook Express is installed on your computer and the "Make Outlook Express my default Simple MAPI client" check box is selected.
- You have uninstalled Outlook 97, Outlook 98, Office 97 or Office 98. Uninstalling these products removes the Mapi32.dll file, which is needed to share folders, from your computer.
RESOLUTION
To work around this problem, use the appropriate method:
Using Outlook Express
- Restart your computer.
- Click Start, point to Programs, point to Internet Explorer, and then click Outlook Express.
- On the Tools menu, click Options.
- On the General tab, click the "Make Outlook Express my default Simple MAPI client" check box to clear it, and then click Apply.
- Click OK when you receive the following prompt:
The Simple MAPI client has been changed. You may need to restart your machine for the change to take effect.
- Click OK.
NOTE
- If you do not restart your computer in step 1, you may receive the following error message when you click OK: The Simple MAPI Client could not be changed because MAPI is already in use. Close all mail enabled applications and restart your machine. Then retry this option. This error message may occur even if Outlook Express is the only mail program that is currently running.
- Quit Outlook Express, and then restart your computer.
Uninstalled Outlook 97/98 and Office 97/98
Extract a new copy of the Mapi32.dll file to the Windows\System folder.
The Mapi32.dll file can be found in the following locations:

MORE INFORMATION
If you want to keep Outlook Express as your default Simple messaging application programming interface (MAPI) client, add all user-level sharing permissions while the "Make Outlook Express my default Simple MAPI client" check box is cleared. Once all user-level sharing permissions are added, restart your computer, and then click the "Make Outlook Express my default Simple MAPI client" check box to select it.
When the "Make Outlook Express my default Simple MAPI client" check box is selected, Outlook Express is used when you send a document from within another program by clicking Send on the File menu.
