M365 Changelog: (Updated) Basic auth retirement for Office 365 Reporting Web Service

MC477010 – Updated February 6, 2023: Microsoft has updated the timeline below. Thank you for your patience.

Microsoft originally communicated this change in MC318316 (January 2022). The company has updated the timeline for this change and are now ready to proceed.

Currently, users accessing Reporting Web service use “Basic Authentication” and must provide their credentials. With this feature update, Microsoft will improve the security of your tenant by replacing “Basic Authentication” access in favor of the recommended OAuth user interface which is where Microsoft will continue to invest our development resources.

Key points

  • Timing: Rollout will begin in late January and is expected to be complete by mid-March (previously late February).

How this will affect your organization:

No immediate action required. Users could start migrating their programmatic access to Office 365 Reporting Web Service from “Basic Authentication” to “OAuth”.

What you need to do to prepare:

You might want to notify your users about this change and update your training and documentation as appropriate.
