 Last reviewed: February 3, 1998
Article ID: Q162670

The information in this article applies to:
  • Microsoft Exchange Windows 3.x client, version 4.0

SUMMARY

The error message: 

   The MAPI spooler could not be started. Close and restart all mail-
   enabled applications. MAPI 1.0[000004c7]
appears when you start a 16-bit Exchange Client. In most cases, this is a conventional memory issue.

WORKAROUND

To work around this problem:

  1. Optimize conventional memory as much as possible (for example by means of MEMMAKER from MS-DOS 6.0/6.2).

  2. Disable all real mode device drivers and TSR programs you do not need.

  3. Disable automatically started applications by WIN.INI via RUN=, LOAD=).

  4. Use Program Manager (PROGMAN.EXE) as your shell.

  5. Change the order in which your programs or drivers load in order to minimize memory fragmentation.

  6. Remove as many 3rd-party Windows drivers or virtual device drivers (VxDs) as possible.

  7. Using Windows for Workgroups uncheck the option "Use Network DDE" in control panel app network.

  8. Configure the computer using NetBEUI or TCP/IP if possible.

  9. Test a Win16 computer by means of the Memvalet utility (this forces DLLs to load into upper memory). The utility is unsupported and should only be used after the normal troubleshooting steps have failed. (ftp://ftp.microsoft.com/bussys/exchange/exchange-unsup-ed/Memval.zip)
