Invitees accept the meeting, but the organiser doesn't see the response
Tracking info goes missing on forwards, replies from a different account, or cross-tenant without federation.
Try this first
- 1Ask the invitee whether they forwarded the meeting, that breaks tracking
- 2Confirm the response comes from the invited account, not a delegate
- 3Cross-tenant: federation/free-busy must be enabled between tenants
- 4In Outlook: View > Tracking to see all responses
When to bring us in
On shared calendars, tracking lands in the organiser mailbox, not the delegate.
