Frequently Asked Questions

Why did my Microsoft 365 admin center theme change unexpectedly?

Theme changes can occur due to major Microsoft system updates, browser caching issues, or if another administrator accidentally modifies the organization profile settings.

Do I need global admin rights to change the Microsoft 365 theme?

Yes, you typically need Global Administrator credentials or a specialized admin role to access and modify the Org settings and Organization profile in the Microsoft 365 admin center.

Will resetting the custom theme affect my SharePoint site contents?

No. Resetting the custom theme in the Microsoft 365 admin center only affects the global navigation bar and administrative interface colors; it does not alter your actual SharePoint site content, data, or custom site templates.

Can individual users override the organization's custom theme?

While the admin center sets the default global theme for the organization, individual users can sometimes customize their own Microsoft 365 theme settings via their personal profile settings (the gear icon in the top right corner of the suite bar), which will override the admin default for their view.
