\** The IPF may also occur in DAO350.dll. The same steps used in this article
\** corrected the error. -- V-1ROBR.
\**
\** It has been reported that if certain entries are missing from the AUTOEXEC.BAT
\** file you will get this error. Check to see if these lines are in the
\** AUTOEXEC.BAT. Add them if they are missing. At the top of the AUTOEXEC.BAT file
\** add theses two lines:
\**
\**
\**
\**
\** C:\PROGRA~1\NETWOR~1\MCAFEE~1\SCAN.EXE C:\
\** @IF ERRORLEVEL 1 PAUSE
\**
\**
\**
\**
\** At the end of the AUTOEXEC.BAT file add these two lines:
\**
\**
\**
\**
\** REM Environment Setting For McAfee VirusScan
\** SET PATH=%PATH%;C:\PROGRA~1\NETWOR~1\MCAFEE~1
\**
\**
\**
\**
\** Save the AUTOEXEC.BAT file and restart the computer. -- a-jivey
\**
\** This problem may also occur following a corrupt install of McAfee's Virus Scan.
\** After a corrupt install of McAfee, when you open Outlook you may receive an
\** error message that McAfee did not install, or could not install a *.dll file.
\**
\** After such a message, Exchange Scan may not show in the Add-in Manager, but you
\** may receive the same error message noted above. If you uninstall McAfee, the
\** error message goes away. -- a-dgrant
\**
\** Noticed after user installed McAfee e-mail scan add-in, they no longer see
\** Capital "L" in the banner for folder names -- not in the folder list, but in the
\** heading where you see the folder name in gray banner on top left. After
\** disabling e-mail scan, the "L"s mysteriously reappeared! -- V-1NWHE.
\**
\** This may also happen when using OL97. -- KEAZ487.
