Exchange issues in User Creation Template - 6.5.8

Technician is receiving "Alert Message - 'Mail Alias' is a mandatory field. You can't leave it empty."

The field and tab is silently active in the template and has a naming scheme specified.

Creating the user myself, the user gets created with the following errors:

Error Code 80072030 : Error in setting attributes, There is no such object on the server.
Error Code 80072030 : Setting values for Exchange attributes: Error in setting attributes, There is no such object on the server.
