Copilot in Outlook AMA

How can we enable Copilot to have better knowledge of what's in our Outlook Inbox? Almost 1 year on from the launch of M365 Copilot, it's still slightly depressing to ask Copilot "how many emails do I have in my inbox, and what's most important" and to be told "You have six emails in your inbox, and here are the most important ones", when actually there are several hundred emails in my inbox... When will M365 Copilot be linked to a properly indexed search of our Outlook inboxes, and when should we expect to be able to rely on it for help with prioritisation - based on a complete search of emails, not a small subset?
