When you use AADS for contacts, following are the limitations you face while you edit the contact details fields:
You cannot edit the email address for a contact in the Enterprise directory.
When you add contacts from the Enterprise directory, you cannot edit the detail fields using the Avaya Workplace Client. You can still make the changes using the J100 phones, but these changes reflect on other J100 phones, not on the Avaya Workplace Client in the MDA setup.
