Hello. I have been trying to assign an Appointment (Activity entity) in CRM 4.0. The user I tried assigning to has the System Administrator role so they should be able to receive it. However, I am greeted with the below error message:

I have been using a CRM user account called 'User Two' for testing purposes. I have given this user the 'Assign' right for the Activity entity:

The Appointment entity has the following three tabs:



As can be seen, the only lookup field on the Appointment form is for the Owner (User). I have also given the 'Appended To' right to the User entity to allow the Owner lookup value to be added to the Appointment entity, but I am still getting the same error message mentioned earlier on.

Are there any other permissions which I am missing which are needed to allow the assigning of an Appointment to another user?
