MS-700 deep review — September 28, 2026

Read the whole guide and mapped all 97 detailed objectives in twelve groups from the published October 27 revision. Preserve the accepted July 29 objective/status snapshots until the change takes effect. Domain weights are unchanged. Credential metadata lists 100 minutes and seven languages; the course lists four days and English.

Learning changes

Five worked examples cover directional bandwidth, policy precedence, distinct app audiences, callback timing and session-versus-participant rates. Add two labs (ten total) and eight answers (44 total). Update network tools/QoS, roles and workload boundaries, granular federation/shared-channel access, app migration/consent, room identity, VDI support, unified events/Copilot, voice funding and current telemetry behavior. All examples are synthetic; no tenant, device, network executable, call, flow or media lab was run.

Source decisions

The updated developer announcement provides the controlling connector retirement update. Older text remains on that page and the platform overview; readers must select the dated update rather than the original deadline. Unresolved: its private-channel support statement differs from the platform overview. Keep rollout instructions conditional on current cloud, identity, entry point and observed delivery; source reachability does not resolve the difference.

The July Teams blog was read as main article text, with app-request and room-authentication exercises selected. The legacy Rooms authentication article does not establish a complete new passwordless migration procedure. Comments, embedded demos and unrelated device announcements were not used as authoritative implementation evidence.

Catalog comparison verified four Learn paths/20 modules, five Pluralsight course listings totaling 18h58, and MeasureUp’s 155-question public listing. Learn runtimes retained only as historical estimates; four O’Reilly/Udemy pages were blocked. Paid lessons/questions, course completeness, originality and interactive practice were not verified. Do not adopt vendor exam-duration or question-count claims over the credential page.

Follow-up and validation

Schedule the October blueprint recheck, Windows VDI support/end-of-availability milestones, private-channel documentation reconciliation, and live-events grace-period check. Repository validation, unit tests, strict site build and generated-site validation must pass before publication; final results are in the operation record ADLC_Docs/operations/2026-09-28-ms-700-deep-review.json. The review is same-context AI work; independent human review remains pending.
