Service Accounts not working with Office365 and Graph

Our API v3 uses Microsoft Graph to connect to Office365 mailboxes. Microsoft Graph does not support Service accounts.

Instead, Microsoft Graph supports granting Azure apps permission to access the mailboxes itself. Documentation on how to do that can be found here: https://learn.microsoft.com/en-us/graph/auth-v2-service?tabs=http

Our API v2 used Exchange Web Services to connect to Office365 mailboxes. Exchange Web Services supported Service accounts.
