App registration for Microsoft Graph

To enable OAuth 2.0 authentication, Synchronizer must be registered as a Microsoft Azure app for the tenant.

To complete the app registration:

  1. Use your web browser to navigate to the Microsoft Azure portal at https://portal.azure.com/.
  2. Select App registrations and click + New registration.

    Specify the required information for the new app, such as Name and Supported account type and complete the registration process.

  3. On the application's Overview page, copy the value of the Application (client) ID and Directory (tenant) ID and save them.

    These values are required when you configure Exchange Synchronizer in LN. The Application (client) ID is the Client ID and the Directory (tenant) ID is the Azure Tenant in the MS Exchange Synchronization Settings.

  4. Select API permissions and add a permission for Microsoft Graph. Ensure that the permissions include Calendars.ReadWrite and Contacts.ReadWrite assuming both calendar and contact synchronizations are within the scope of your project.
  5. Under Certificates & secrets, create a client secret and copy the generated value for later use when you configure Exchange Synchronizer in LN. This secret is the Client Secret in the MS Exchange Synchronization Settings.
