Step 3. Select Azure Region and Authentication Method
At this step of the wizard, select a region and authentication method.
To select a region and authentication method, do the following:
- From the Region drop-down list, select a Microsoft Azure region your Microsoft 365 organization belongs to.
Keep in mind that you cannot select legacy Microsoft Azure Germany region for modern app-only authentication.
- Select the Modern authentication option to use Azure AD application to connect to your Microsoft 365 organization with enabled security defaults.
Make sure to leave the Allow for using legacy authentication protocols check box cleared. This check box allows you to add a Microsoft 365 organization with disabled security defaults. For more information, see Adding Organizations with Modern Authentication and Legacy Protocols.
If you selected the Teams chats check box at the previous step of the wizard, the Modern authentication option is only available.
