Set preferences for Outlook for Mac

Applies to: Outlook for Mac, Outlook Long Term Service Channel (LTSC) for Mac 2024, Outlook LTSC for Mac 2021

The following preferences can be used to simplify account setup for Microsoft 365 mailboxes, help protect company data, and support a streamlined user experience.

As an IT admin, you can provide Mac users in your organization with a standard set of preferences for Outlook in either of the following ways:

• Set a default preference, which users can change.
• Force a particular preference, which users can’t change.

Most preferences can be changed using the Terminal, or via a script. For example:

defaults write com.microsoft.Outlook DefaultWeatherLocation -string 'Paris, France'

When you change preferences in Terminal, users can override the value in the Outlook app. To change the value and enforce it so that users can't override it, use a Configuration Profile.

All of these keys are CFPreferences-compatible, which means that they can be set by using enterprise management (MDM) software for Mac, such as Microsoft Intune and Jamf Pro.
