  • Microsoft Windows NT Workstation 3.1
This article was previously published under Q101236

SUMMARY

If you run the Windows 3.1 version of Microsoft Mail 3.0 or 3.2, instead of the 32-bit version of Mail included with Windows NT, you will need to enter the following commands at any command prompt after installing 16-bit Mail to enable other 16-bit programs to use MAPI functionality:

c:
cd \winnt\system32
ren mapi.dll mapi.sav
copy c:\windows\system\mapi.dll

Note: These commands assume that Windows 3.1 was installed to the C:\WINDOWS directory and Windows NT is in the C:\WINNT directory.
