As an IT admin, you may want to provide Outlook for Mac users in your organization with a standard set of preferences in either of the following ways:
- Set a default preference, which users can change.
- Force a particular preference, which users can’t change.
The following preferences can be used to simplify account setup for Office 365 mailboxes, help protect company data, and support a streamlined user experience.
