the safe and blocked lists combined have a limit of approx 2000 names.
have you rebooted after it started? That seems to fix it for some people.
If you created a new profile in Outlook 2003 or 2007 and used the pst it
created with the profile, you have a Unicode pst so file size or item count
per folder won't matter. If you are using a pst created in an older version
of outlook: If the folders have too many items you will not be able use that
folder and if the deleted is 'full' you may have problems working in other
folders. (16,000 in a pst made in outlook 2000 to 65,000 + in newer
versions) If you are using a pst created in an older version of outlook, it
can not exceed 2 GB in total file size.

I have rebooted several times. I have not changed anything since I have
downloaded Outlook 2003. I just want it to work again. And I don't know
what pst is.
