Insufficient Permissions to Create Tasks

[Nicole]

Hi,

Exchange 5.5, Windows 2000, Outlook 2000. I have a user
who is trying to create tasks and he gets a message that
says that he does not have permission to do this. He can
edit tasks and delete tasks, but not create them. We've
run the repair utility, reinstalled, thought that it had
to do with the PALM software and removed that, and there
has been no change. Any help would be much appreciated!

Thanks!
