This is a known issue.
You may notice that old meetings you organized for the future are still on your calendar, even after you tried to cancel them and switched to your new AIR account. This is a common challenge during migration that requires a specific cleanup step.
The Problem: Ownership is Lost
Your mailbox moved from the Owens Design system to the AIR system.
Fixed Identity: When you create a meeting, the old system assigns a secret, permanent "owner ID" to that meeting, linked specifically to your old account.
New Mailbox: When your mailbox moved to AIR, you received a completely new identity, even though it's the same person.
No Rights: Because your new mailbox doesn't match the meeting's original "owner ID," the system sees you as just another attendee, not the organizer.
Failed Cancellation: When you try to cancel the meeting from your new account, the cancellation notice fails to work correctly across the system, leaving the meeting stuck on everyone's calendar.
? Note: Migration tools (like BitTitan) move your data, but they cannot legally transfer this deep "owner ID" across company systems. This is a Microsoft system limitation.
The Solution: Cancel and Recreate
You must use the Cancel and Recreate method to force the old meetings off the calendar and establish a new, clean meeting link.
Cancel the Old Meeting: Open the old meeting in your Outlook Calendar and send a cancellation notice.
Ask for Manual Deletion (Optional): If the meeting won't leave people's calendars, send a separate email to attendees asking them to manually delete the old, stuck meeting from their calendars.
Create New: Schedule an entirely new meeting (or meeting series) using your AIR account and send the new invite. This creates a clean, functional link that you fully own.
This ensures you have full control over your calendar going forward!
