Observation time is not publication time, and a comparison does not establish an effective date. Full source bodies are not published; this page holds generated summaries, section headings and, as the page's license allows, Microsoft's changed wording. A documentation edit does not confirm feature availability in an environment.

This is an earlier observation; review the latest in My radar.

Timeline

From the capture of 6 Oct 17:57 UTC · an earlier observation

Legacy capture: table structure or oversized sections are unavailable for extraction

Microsoft's revision log on this page · 11 entries

Dates from the page's own change log or history section. They describe earlier edits, not upcoming policy.

Extracted automatically from Microsoft's wording. Confirm dates, conditions and whether they apply to you in the source before acting; a month or quarter is a window, not a day.

How this timeline changed

Changes between ChangeIntel's readings of the page, between commits of its source file where Microsoft publishes it, in Internet Archive copies of pages that keep no other history, and entries from Microsoft's own change log (dated as Microsoft dates them). Edits between readings that neither records are unknown.

Earlier unavailable versions and edits between checks are unknown. A missing statement requires review; it does not mean the policy was cancelled. Recovered historical statements are not original revision snapshots.

Compact evidence remains available after full document bodies expire. Earlier extractions can have different vocabulary or capture limitations.

Microsoft's edits
