Customize The Login Page Of Office 365

Any organization that is using Office 365 will want to customize the main login screen for all their users in order to give them a more consistent and familiar experience. Within Office 365, achieving that is simple and straightforward. The organization logo, color schemes, images, etc. can be set on the login page.

However, you must be a global administrator to do that. It must also be noted that all branding options are NOT mandatory. For the options which have no specified styles/images, it will resort to the defaults of Office 365. The steps below explain how to make the customization.

Step 1

Open https://www.office.com and log in using your credentials.

Step 2

After login, open Azure Active Directory Admin Center using the following navigation.
