Outlook 2003 won't run - ecf error

April 3, 2011 at 09:09:27
Specs: Windows XP Media SP3
Outlook 2003 won't open. (XP Medica Centre SP3)
Error message: I try to open it in safe mode I get this message: the extension configuration
file "C:\ProgramFiles\MicrosoftOffice\Office11\ADDINS\msspc-ecf" could not be
installed. There is an error in the syntax or format of the file.

I have tried:
Reinstalling Office.
Starting Outlook in safe mode (run>Outlook.exe/safe)

Deleting/renaming the extend.dat file
Going to the Registry where the MSKB article kb/167264
suggests I go to HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\Client\Extensions

but all I see is
Exchange Extensions
Remote Exchange Extensions
Server Scripting

Which one is the one I'm supposed to delete?

Or, any other suggestions

Browse to the outlook executable, open the Properties sheet and make sure all Compatibility options are unchecked.

Thanks...now it says:

Cannot start Microsoft Office Outlook. Unable to open the Outlook Window. The set of folders could not be opened, the server is not available. Contract administrator if the problem persists.

Somehow, it seems, the profile has been corrupted. Do you have a restore point you can go back to? If that doesn't work, I'll refer you to this thread which has some solutions that look good. Before I did anything, I would back up the data.

You can export/import and key hierarchy. But I'm not clear on what OC has to do with this. And you would run the risk of pointing to a folder or profile that doesn't exist on the second machine. Unless you are sure of what you're doing and have good reason, I'd be very hesitant.

I actually dug up a MS KB article which suggested recreating a profile through control panel.....and this seems to have done the trick...- - for now LOL
thanks for offering some ideas....
