12th December 2017 – Please note that this option has now been removed from the advanced settings section. This means that setting a URL to be re-directed to when a user has logged out is no longer available! Really sorry if you came here hoping to follow these instructions and set this up!
To change the website that you are automatically redirected to when you logout of Office 365, follow these steps.
Go to https://login.microsoftonline.com and log on as your administrator user. Once you have logged on, click on the tile icon in the top left hand corner of the window.
In the list of available icons that appear, click on the “Admin” icon.
Scroll down the left hand side of the screen and place your mouse over the admin centers icon.
When you do this, a second menu will appear. On this menu, click on the line that reads “Azure AD”.
A new tab will open in your browser. If the screen looks like this
click on the line that reads “Check out the new portal”
and then click on the “Launch” button.
This will take you to the azure portal page.
On the left hand side of the page, click on the line that reads “Azure Active Directory”.
The page will change to show you all the Azure Active Directory settings.
Click on the line that reads “Company branding”.
The screen to the right of “Company branding” will change and show you the available options.
Click on “Edit company branding”.
The screen to the right will change to show you the available options.
Scroll down this part of the page until you can see the “Advanced settings” section.
The two fields “Post-signout link label” and “Post-signout link URL” are the fields that you need to change.
Enter the label and URL that you want to use and then click on the “Save” icon.
The branding settings will then be updated. You can now log out from the admin center.
Now, when a normal user next connects to office 365 and then logs out, they will be taken to the URL that you have saved in the above settings.
