Hello, I have a issue with an Outlook shared tasks list. First, I have given "owner" permissions to the users of this shared task list. The problem I have is that the shared users cannot create any new categories within the task list because the New and Rename button are "grey'ed" out and I am not able to click on them.



I have tried creating a new "test" task list, to see if the issue was with that specific task however, I still arrive at the same problem.

I have shared a task list before and given owner permissions to the shared users and not arrived at this problem.

Any solutions?
