Configure organization-wide settings

Change organization-wide settings so external sharing is limited to existing guests, set tenant discovery to off, disable anonymous join links, and enforce multi-factor authentication for all accounts by next Friday. Before making these org changes, confirm which three business units require anonymous access for workshops and capture their approval in writing.

Before I roll out org-wide settings to the whole company, make the configuration easy for leaders to approve: surface the MFA enforcement timeline, show who will be blocked by disabling anonymous links, present a fallback plan for training webinars, and flag conflicts with existing vendor integrations that rely on anonymous access. Identify the single change most likely to delay sign-off.

I disabled anonymous join links globally to tighten control. HR replies that Friday's company town hall relies on an anonymous link for offsite employees. I don't know whether HR can switch to authenticated invites or extend a temporary exception. What's the most likely cause and the recommended immediate step to avoid cancelling the town hall while keeping controls in place?

We roll out org settings and repeatedly get emergency exceptions for events like town halls and vendor demos. Where are we losing credibility and creating fire drills? Recommend one habit change—what approval or testing step we should build into policy rollouts to prevent last-minute crises and save admin time?
