3 Simple Steps to Customize Your Office365 Login Page

A custom Office 365 login page that matches your branding and design will greet your users with a familiar experience and welcomes them to their portal.  This doesn't take long to set up and makes for a much nicer login experience.

Step 1: Prepare Your Images

For this example, you'll need two images.  We are setting the Main Login Image and the Banner Image.  You may need a designer to help get the images set to the right dimensions and not exceed the file size limits.

  • Main Login Image

    • 1420 x 1200 px
    • Maximum size of 500 KB
    • File Type PNG or JPG
  • Banner Image

    • 60 x 280 px
    • Maximum size of 10 KB
    • File Type PNG or JPG
  • See the example below for examples of both of the above images
