How to force Outlook to re-read add-ins from registry?

[Mark Beiley]

I'm trying to get Outlook 2003 to re-read the installed add-ins from the
registry, but it doesn't always work reliably. I write:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Client\Extensions\Outlook
Setup Extension

to

4.0;Outxxx.dll;7;000000000000000;0000000000;OutXXX

I've found that this doesn't always work. I haven't been able to figure out
exactly when/why, but there have definitely been cases where it doesn't
re-read the add-ins from the registry. I've read there is a file
"extend.dat" that you can delete, which is Outlook's cache of add-ins? I
haven't been able to find such a file? Is this still the name of the cache
file under Outlook 2003? Any other suggestions on how to force Outlook to
re-read the add-ins listed in the registry?

Thanks,

I believe that value should be:

"4.0;emsuix32.dll;7;011111111111110;1111011100"

This key always worked for me. Make sure outlook.exe is not running in the
task manager when creating this key.
extend.dat files are created for each user, look for them in C:\Documents
and Settings\<username>\Local Settings\Application Data\Microsoft\Outlook.
