Until now, no matter the effort you invested in branding your Office 365 sites and keep your collaborators involved with your company brand, the Sign In page was impossible to change.

Now if your Office 365 environment is associated with the Azure Active Directory you are able to customize the appearance of the Sign In page so that it includes your company logo, color scheme and a few other settings.

# Page Elements Location on the page
1 Large Illustration / Background Color Shown at the left of the page. Replaces the image that would normally be displayed by the destination site that your users are signing in to. The Background Color may be shown in place of the Large Illustration on low bandwidth connections, or on very narrow screens.
2 Banner Logo Shown at the top-right of the page. Replaces the logo that would normally be displayed by the destination site that your users are signing in to (For example. Office 365 or Azure).
3 Sign In Page Text Shown above the page footer when you need to convey helpful information to your users before they sign in with their organizational account. For example, you may want to include the phone number to your help desk, or a legal statement.

The customization could take up to one hour to be applied to your Sign In page.

After your first customization have been saved, an administrator also has the option to add localized versions of each element, for different languages/locales, this means that you can have multiple Sign In pages for your collaborators around the world.
