The Setup if the following:
Windows XP SP2
Outlook 2003 SP2
Connecting to SBS 2003 SP1 / Exchange 2003 SP1
Mail is stored in Exchange not PST
Profile only contains Microsoft exchange

Ok when opening Outlook it pops up I see the folder list then Outlook
closes. Oddly there is an outlook systray icon next to the clock that goes
away when the mouse goes over it.

So far I have tried the following, with zero success:

1) Run Office update from microsoft.com/office
2) Delete and recreate the outlook profile
3) Uninstall and reinstall Outlook 2003 w/ all patches
4) Launch Outlook in /safe mode
5) Delete .ost files
6) Run Filemon to see if there were any file access denies. There were none
7) Launch Outlook with /cleanprofile switch
8) Launch Outlook with /nopollmail
9) Launch Outlook with /noextensions
10) Launch Outlook with /safe:3 & /safe:4
11) Opened Outlook on another computer as the same user w/ same worksation
permissions w/o any issues
12) Opened Outlook on Problem Workstation as administrator to administrator
mailbox, problem reproduced.

I am not sure if applies but... The filemon also shows Outlook.exe queries
multiple versions of IDAPI32.DLL. One of these is in the ADP payroll
software directory, which also was installed before the error occurred. I
know the easy "fix" is to uninstall the new ADP software. This is not an
option. I have 5 other identical PCs managed by SBS and WSUS and they do
not
have an issue.

Are there any clues what could be going on? Is there any outlook debugging
modes that can cause a error log output so maybe I can see what is going on?
