Who it is for

For everyone after K2 whose application should use mail, calendar, files or Teams from Microsoft 365 and who wants to grant only the smallest rights needed.

Prerequisites

K2 (web API, sign-in with Entra ID, background services, mail as a port) or the placement test. K3 helps with managed identity. The exercises that use a tenant need a test tenant, never a production tenant.

Afterward, you can

  • Call Graph with the SDK and use query options and paging correctly
  • Justify the access type and the smallest permission for every call and scope mailboxes
  • Send and read mail, read and write appointments
  • Synchronize appointments between the Kladde and Outlook with delta queries and change notifications
  • Store files and send messages to a Teams channel
  • Handle throttling, batches and errors and test the synchronization without a tenant

Final project: the Kladde

What the Kladde can do after this course

The Kladde sends mail through Graph, synchronizes its appointments with the office's Outlook calendar and reports in a Teams channel.

The course ends with a module exam: the core of a synchronization against stand-ins and a justified list of permissions.
