Watching for changes since 26 Sep 2026. Revisions Microsoft made before then were not observed, which does not mean there were none.
Nothing about Outlook yet in: dates in the next 12 months, versions.
A change belongs to Outlook when it comes from a source about the product or one of its names (Outlook, Microsoft Outlook), when a roadmap entry, Windows release, or known issue lists it, or when an MSRC CVE, CISA entry, or lifecycle date names it. Another product's notes and community posts that only mention Outlook are listed under "Also mentioned in" and are not counted as its changes. Sources marked quiet are about Outlook alone and have had nothing new for 30 days; check the source before reading silence as "no change".
