  4. Configure BEMS to communicate with a Microsoft 365 environment using Microsoft Graph API

Configure
BEMS
 to communicate with a
Microsoft 365
 environment using
Microsoft Graph
 API

Complete this task only if your environment requires new client app registrations. Optionally, you can update an existing app registration.
Before
BEMS
 can send email notifications to users' devices, it must subscribe to changes on a user's mailbox. You can configure
BEMS
 to subscribe to mailboxes using Microsoft Graph API.
BEMS
 subscribes to the
Microsoft Graph
 API change notifications using webhooks. You can configure
BEMS
 to use the
Microsoft Graph
 API in the following scenarios:
  • Your
    BEMS
     is configured to use modern authentication.
  • Your
    BEMS
     connects with
    Microsoft 365
     (Exchange Online) mailboxes.
For information on configuring email notifications for
BlackBerry Work
 using
BEMS
 Cloud, see the BlackBerry Work Administration content.
