Forwarded recurring meeting occurrences don't grant transcript access via onlineMeetings API

Issue

The documentation for onlineMeetings and meeting transcripts does not mention a behavioral difference between single meetings and recurring meeting occurrences when attendees are added via forwarding.

Observed behavior:

Scenario	Forward + Accept	Calendar shows attendee?	onlineMeetings API access?	Transcript access?
Single meeting	✅	✅	✅ 200 OK	✅ Works
Recurring occurrence	✅	✅	❌ 403 Forbidden	❌ Blocked
Scenario	Forward + Accept	Calendar shows attendee?	onlineMeetings API access?	Transcript access?
Single meeting	✅	✅	✅ 200 OK	✅ Works
Recurring occurrence	✅	✅	❌ 403 Forbidden	❌ Blocked

When a single occurrence of a recurring meeting is forwarded to a new attendee:

• The attendee appears on the calendar event for that occurrence
• But the onlineMeetings resource does not reflect them as a participant
• GET /me/onlineMeetings?$filter=JoinWebUrl eq '...' returns 403 with code 3003
• This blocks all downstream operations (transcript retrieval, meeting metadata, etc.)

Request

Please either:

1. Document this limitation in the onlineMeetings and/or callTranscript documentation, so developers can inform users about the constraint
2. Or confirm this is unintended behavior so it can be tracked as a bug

Impact: This affects enterprise applications that access meeting transcripts programmatically. Forwarding individual occurrences of recurring meetings is a very common pattern in organizations.

Reproduction steps: See Microsoft Q&A post (to be linked after filing).
