Configure alternate authentication and
Office 365
resource URLs

If your organization uses alternate login and
Office 365
resource URLs, you must configure the alternate URLs in the app configuration for each required app. For example, the U.S. Government uses alternate login and
Office 365
resource URLs. The default URLs are as follows:
  • Login URL: login.microsoftonline.com
  • Office 365 resource URL: outlook.office365.com
The U.S. Government uses the following URLs:
  • Login URL: login.microsoftonline.us
  • Office 365 resource URL: outlook.office365.us
For more information, see the
Microsoft
resource National clouds.
In addition to configuring the alternate login and Office 365 resource URLs, you must also ensure that your routing and connectivity profiles are configured appropriately and can access the alternate URLs.
Perform these steps on the app configuration of each required app.
  1. In the
    Office 365 Sign On URL
    field, type the login URL for your organization.
  2. In the
    Office 365 Resource
    field, type the Office 365 resource URL for your organization.
  3. In the
    Exchange ActiveSync Settings
    area, in the
    ActiveSync Server
    field, type the Office 365 resource URL for your organization.
  4. Save the app configuration.
