87. Outlook won't shut down, the outlook.exe is still in the task manager.

Do you have any programs that access Outlook data?
Antispam scanners, pda synchronization applications, winfax are just a few of these. They need to be closed before closing Outlook.
Try opening the mailbox in Outlook using the ".../CleanFreeBusy" switch. The link below to "OL2002: Additional Command-Line Switches" will give you the instructions on how to use it. http://support.microsoft.com/default.aspx?scid=KB;en-us;296192&

88. When closing Outlook 2000 it hangs on the "please wait while outlook closes" message.

You need a hotfix for your Outlook 2000:

89. After launching Outlook it opens for about a second and then it closes.

Does Outlook start in safe mode?
(select Start > Run; type: outlook.exe/safe > OK button)
If the answer is yes, then try renaming/deleting the file named outcmd.dat.
This file tracks menu/toolbar customizations and does get corrupted over a period of time.

90. When I start Outlook 2003 it always hangs at the step of "migrating account settings."

Rename the outcmd.dat file.
