Architecture:
BEMS
notification flow using the
Microsoft Graph
API

In 2022,

Microsoft

started to deprecate the

Microsoft Exchange Web Services

(EWS) for Microsoft

Microsoft Exchange Online

APIs replacing the EWS with

Microsoft Graph

. For more information, visit techcommunity.microsoft.com and read 'Upcoming API Deprecations in Exchange Web Services for Exchange Online'.

This diagram shows how

BEMS

uses

Microsoft Graph

to send notifications to devices.

Component name	Description
BEMS	BEMS consolidates several BEMS services used to send work data to and from BlackBerry Dynamics apps, including BlackBerry Push Notifications ( BlackBerry Mail), BlackBerry Connect , BlackBerry Presence , and BlackBerry Docs . BEMS listens for notification URI sent by the Microsoft Graph API.
Reverse proxy server	The reverse proxy server receives the Microsoft Graph connection and forwards the connection to the private BEMS URI.
Microsoft Graph	Microsoft Graph is a RESTful web API that allows you to communicate with Microsoft Cloud service resources.

In the

BEMS

console (Mail > Microsoft Graph), you add the External Notification URL that the

Microsoft Graph

API will use to initiate connections to the reverse proxy server.

The

Microsoft Graph

API initiates connections to your organization’s reverse proxy using the provided External Notification URL.

The reverse proxy server intercepts the

Microsoft Graph

connection request and translates/routes the connection request to your private

BEMS

instance.

BEMS

sends the new notification to the user's

BlackBerry Dynamics

app (for example, BlackBerry Work).
