💡 Our Technical Review in summary
Summary
Microsoft is introducing enhanced branding governance capabilities for SharePoint Online via PowerShell. This update provides tenant administrators with centralized control over site aesthetics, allowing for stricter enforcement of enterprise themes and the ability to disable manual branding changes at the site level. A significant component of this update is the transition to a centralized theme management model for multi-geo environments, where the primary geo serves as the authoritative source for organization-wide themes.
Impact
- Administrative Control: Admins can now enable or disable the “Site branding” page within Site Settings on a per-site basis. When disabled, site managers cannot modify the look and feel of their sites manually.
- Theme Enforcement: Enterprise themes, including advanced multi-color themes, can be applied directly to specific sites using PowerShell cmdlets.
- Multi-Geo Changes: Theme creation is being centralized. New themes must be created in the primary geo; satellite geos will retain existing themes but will be restricted to viewing and applying themes from the primary geo moving forward.
- Automation and Auditing: Branding settings can be integrated into automated site provisioning scripts. Additionally, all branding changes made via PowerShell will be logged, providing an audit trail for governance compliance.
- Brand Center Management: Admins gain the ability to remove existing Brand Centers via PowerShell to facilitate resets or updates to branding controls.
- User Experience: Site owners in “locked-down” sites will lose access to branding customization menus, ensuring a unified corporate identity across the tenant.
Action Required
- Update Tools: Ensure the SharePoint Online Management Shell is updated to the latest version to support the new PowerShell parameters.
- Review Command Documentation: Familiarize the IT team with the updated functionality of
Set-SPOSite,Get-SPOTheme, andSet-SPOWebTheme. - Audit Satellite Geos: If operating in a multi-geo environment, identify themes currently stored in satellite geos, as the ability to create new ones there will be deprecated.
- Update Provisioning Scripts: Modify internal site creation scripts to include specific branding and theme parameters to ensure new sites are compliant upon launch.
- Internal Communication: Inform site owners and stakeholders about the new governance policies, especially if the “Site branding” settings will be disabled for certain site collections.
- Monitor Rollout: Track the deployment timeline, with General Availability expected to complete by late February 2026.

[Introduction]

This message is associated with Roadmap ID 526794.
[When this will happen:]
- Targeted Release (Worldwide): Begins late November 2025, completes mid-December 2025
- General Availability (Worldwide, GCC, GCC High, DoD): Begins end of February 2026 (previously mid-January), completes end of February 2026 (previously late January)
[How this affects your organization:]
Who is affected: Tenant admins managing SharePoint Online branding and governance.
What will happen:
- Admins can disable or enable custom site branding per site using PowerShell.
- When site branding is disabled, site managers lose access to Site branding page in Site Settings.
- Admins can apply enterprise themes (including multi-color themes) to specific sites via PowerShell.
- Branding changes made via PowerShell are tracked for audit and accountability.
- New site creation scripts can include branding settings to ensure consistency from launch.
- Admins can remove existing Brand Center via PowerShell.
- Theme management via PowerShell is transitioning to a centralized model:
- The primary geo will act as the central location for organization-wide theme creation and management.
- Satellite geos will be able to view and apply themes from the primary geo using
Get-SPOThemeandSet-SPOWebThemecmdlets. - Themes previously created in satellite geos will remain available, but creating new themes in satellite geos will no longer be supported.
[Here’s what’s new:]
- Consistent branding enforcement: Admins can disable or enable custom branding per site. When disabled, site managers lose access to Site branding page in Site Settings.
- Automated theme application: Apply approved enterprise themes (including multi-color themes) to specific sites using PowerShell.

- Automated site creation with branding: Embed theme settings directly into site creation scripts to ensure new sites launch with consistent branding.
- Easier Brand Center management: Admins can remove an existing Brand Center via PowerShell to reset or update branding controls.
- Centralized theme management across geos: Themes created in the primary geo are visible and applicable in satellite geos. Satellite geos can apply but not create new themes going forward.
[What you can do to prepare:]
- Review PowerShell documentation:
- Upgrade your SharePoint Online Management Shell to the latest version after rollout.
- Communicate branding governance changes to your SharePoint admin team.
- Update internal documentation to reflect new PowerShell capabilities and theme management model.
