Once you have signed up and set up Office 365, the sign-in page you use (https://login.microsoftonline.com) shows a standard image, logo and information.

You may not realise but once you have entered your email address in this field

And before you have entered your password, it is possible to change this page so that it shows images and information that is more relevant to your business.

On this sign-in page, you can change:
The large image shown on the left hand side of the page:

The logo that is shown above the email address field:

And you can also add some welcome text that will appear in this part of the sign-in page.

If you want to change these settings to something more appropriate for your business, follow these steps:

1. Log on at https://login.microsoftonline.com as the admin user that manages all your company’s office 365 accounts. If you don’t have access to this account, contact your IT administrator to follow these instructions.

2. Once logged on, you will be taken to the admin center which will look something like this:

3. At the bottom left hand corner of this window, click on the admin icon that looks like this:

4. A sub-menu will appear. In this sub-menu, click on the line that reads “Azure AD”.

5. If this is the first time that you have clicked on this link, you will be asked to enter some contact information. If you have clicked on this link before, go to step 10.

6. Enter as many details as possible and then click on the “Sign up” button.

7. Office 365 will then perform some setup tasks which will take a few minutes. It might be a good time to make and enjoy a cup of tea!

8. Once it has finished, the window will change to look like this.

9. Now click on the “Start managing my service” button.

10. You will now be taken to the Azure dashboard. If it looks like this:

11. Click on the text “Check out the new portal”

12. And then click on the “Launch” button

13. This will take you to the latest version of the Azure dashboard.

14. On the left hand side of the screen, click on the line that reads “Azure Active Directory”.

15. The contents of the window will change to show you the available active directory settings.

16. Scroll down the list of options shown on the left hand side of the page and click on the line that reads “Company branding”.

17. The contents of the right hand side of the screen will change to show you your branding options. If this is the first time that you have done this, click on “Configure company branding now”.

18. If you have accessed this before, click on “Edit company branding”.

19. You will now see a list of the available changes that you can make to the log-in page.

20. To change the large image on the left hand side of the log-in page, click on the folder icon located here to choose a new image.

21. Notice that the instructions tell you that the best image size to use is one that is 1420 pixels wide by 1200 pixels high. Also, the image itself has to take up less than 500Kb in storage size though less than 200Kb is recommended. Once you have chosen your image, a thumbnail will be displayed to signify that the image is ok.

22. To change the banner image that is shown in the top right hand corner of the log-in page, click on the second folder icon located here to choose a new image.

23. Notice that the instructions tell you that the best image size to use is one that is 280 pixels wide by 60 pixels high. Also, the image itself has to take up less than 10Kb in storage size. Once you have chosen your image, a thumbnail will be displayed to signify that the image is ok.

24. To add some welcome text to the log-in page, enter the text in the box next to the “Sign-in page text” label.

25. When you are happy with all the changes, click on the “Save” icon at the top of the page.

26. Your company branding details will be updated. That’s it!

27. Logoff from the admin page by clicking on your user details in the top right hand corner of the window and then from the sub-menu that appears, click on “Sign out”.

28. If you now go back back to https://login.microsoftonline.com you will not initially see any changes. The page will look exactly the same as before.

29. That’s because this is a generic page and at this point, Office 365 does not know who you are going to try and log on as so cannot work out which branding images to use. However, once you enter your email address and tab or click into the password field, Office 365 will work out that you have branded images and text available and will show them as you are entering your password.

30. Well done. You have successfully changed the branding images and text when you log-on to Office 365.
