[adhilto]

Prerequisites

• This issue has an informative and human-readable title.

💡 Summary

Update GWS.CALENDAR.3.2v0.5 given recent updates to the GWS admin center.
The current policy indicates that OAUTH 2.0 shall be used. This will clarify the policy to indicate that option M365 Graph option is to be selected.

Motivation and context

The admin center now lets you choose between 3 different types of endpoint:

• M365 (Graph API)
• M365 (Legacy EWS)
• on prem

Only the on prem endpoint still supports password based auth. The graph API is the most secure of the 3 options.

Implementation notes

N/A

Acceptance criteria

• Determine new policy statement. Something like "SHALL use graph API"?
• Update the implementation steps
• Update the ScubaGoggles code if needed

current branch has updated instructions for Graph API. Need to discuss if server on-premises is viable.

Per @mitchelbaker-cisa Decision is to use SHALL and require Graph API.
