Default compose font: Administrators can allow users to change the default font in Outlook for iOS and Android [MC1303717]

Message ID: MC1303717

[Introduction]

To balance organizational branding with user flexibility, administrators will be able to control whether users can change the default compose font in Outlook for iOS and Android. When a default font name or size is set using Microsoft Intune app configuration policies, new configuration keys will allow administrators to decide if users can modify those defaults.

[When this will happen]

General Availability (Worldwide): We will begin rolling out in early June 2026 and expect to complete by late June 2026.

[How this affects your organization]

Who is affected

• Administrators managing Outlook for iOS and Android using Microsoft Intune
• Users only if administrators enable user changes

What will happen

• Today, when a default compose font name or size is configured through Intune app configuration, users cannot change it.
• With this update, administrators will be able to optionally allow users to change:
  • The default font name
  • The default font size
  • Both
• Two new Intune app configuration keys will be available:
  • com.microsoft.outlook.Settings.defaultFontName.UserChangeAllowed
  • com.microsoft.outlook.Settings.defaultFontSize.UserChangeAllowed
• By default:
  • Both keys will be set to false, preserving existing behavior.
  • No changes will occur unless an administrator enables them.
• The keys will apply only when the corresponding default font setting is already configured.
• If a user changes the font:
  • The administrator-configured default will no longer apply for that user.
  • Future administrator updates will not override the user’s selection.
  • There is no automatic reset to the administrator-defined value.
• This feature will be off by default and requires explicit administrator configuration.

[What you can do to prepare]

No action is required to maintain the current locked-font behavior.

Optional (recommended):

• Review your Intune app configuration policies for Outlook for iOS and Android.
• To allow user changes:
  • Set com.microsoft.outlook.Settings.defaultFontName.UserChangeAllowed to true to allow font name changes.
  • Set com.microsoft.outlook.Settings.defaultFontSize.UserChangeAllowed to true to allow font size changes.
• Update internal documentation or helpdesk guidance as appropriate.
