Answer

Running Process Explorer when attempting to start the corrupted Outlook will show that the problem file is NOT MAPI32.dll but MSMAPI32.dll (which Outlook attemtps to load), contrary to the error generated by Windows.  The solution which fixes the corrupt/wrong version of MSMAPI32.dll is this: 

  1. In the C:\Program Files\Common Files\System\MSMAPI\1033 rename MSMAPI32.dll to MSMAPI32.old.
  2. Re-run setup for MS Office and select Reinstall.
  3. Restart Computer.
  4. Run SFC.exe /scannowd to be sure that all the protected Windows system files are OK.
  5. Open Outlook.
