+### Requirement: Outlook Teams meetings can prompt recording start
+Meeting Assistant SHALL provide a disabled-by-default setting that enables scheduled Outlook Classic calendar checks for recording-start prompts.
+
+When scheduled recording prompts are enabled on Windows, Meeting Assistant SHALL periodically read the user's Outlook Classic calendar appointments for the current local day through COM into an in-memory cache.
+
+Meeting Assistant SHALL default the Outlook calendar sync interval to 30 minutes when scheduled recording prompts are enabled.
+
+Meeting Assistant SHALL schedule recording-start prompts from the cached calendar appointments rather than querying Outlook for each prompt.
+
+Meeting Assistant SHALL consider Teams appointments from Outlook calendar data as initial prompt candidates. The detection MAY be extended later for other meeting providers.
+
+When a Teams appointment reaches its scheduled start window, Meeting Assistant SHALL show a native Windows app notification asking whether to record the meeting, with affirmative and negative actions.
+
+Meeting Assistant SHALL prompt at most once per calendar appointment during a local day, regardless of whether the user accepts, declines, or ignores the notification.
+
+If the user accepts the recording prompt while no recording is active, Meeting Assistant SHALL start a new recording normally.
+
+If the user accepts the recording prompt while another recording is active, Meeting Assistant SHALL stop the active recording normally and then start the prompted meeting recording.
+
+When stopping an active recording for an accepted prompt, Meeting Assistant SHALL use the normal stop path so empty or too-short recordings are removed according to existing settings and other completed recordings continue normal transcription, speaker recognition, and summary processing.
