Cause

The language setting could not be set at the user level in CRM due to insufficient user privileges. The user's security role may be missing the Write privilege for the User Settings entity.

  2. Navigate to Settings > Security > Security Roles.

  4. Click the Business Management tab and grant the "Write" privilege for the User Settings entity. User level access is the minimum requirement.

  5. Click Save.

  6. Attempt to connect Microsoft Dynamics CRM for Microsoft Office Outlook again.
