Using MS Graph to Work with O365 Data¶
MS Graph secure API can be used instead of Exchange Web Services to work with MS Office 365 data via Revenue Inbox. MS Graph has several benefits over EWS; it is mostly in demand for high-security corporate environments, as it offers configurable granular data access permissions control. It allows to provide focused access only to specific Office 365 data types, e.g. Contacts, Tasks, Emails, or Calendar items. The same configured MS Graph data access permissions are applied for both Sync app and RI Add-In app; item types with disabled access permissions remain inaccessible by Revenue Inbox.
Also see this Microsoft article to learn more about MS Graph data access control management and security.
This access type can be enabled for a specific org or a specific user in an Org via RI Admin panel: open the Organizations tab > Mailbox access type > set to MS Graph
After user switching from another access type or after a new user is initialized: the user must re-login via O365 OAuth 2.0 in order to refresh the access token.
Another special feature of MS Graph is its full data exchange compatibility with other Microsoft 365 apps: MS Teams, MS Office apps, OneNote, etc. For example, Revenue Inbox can be configured to auto-generate MS Teams room links for its Meeting Scheduler features (Time Slots, Book me). This and other integration scenarios can be considered for for big Enterprise Revenue Inbox customers.
