Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I found out how to go back to the classic version of your M365 subscription (i.e. without Copilot), no need to raise a ticket. This was on another forum post, definitely works in Australia, not sure about other countries. The only issue is that the change won't take effect until the end of your current subscription period, so if you're on annual like me you could be stuck with Copilot for a year (I'm currently trying to get MS to refund the difference):
If you prefer to use Microsoft 365 apps without Copilot at all. Please refer to the following to try to switch back to your old subscription.
- Visitaccount.microsoft.com/services.
- Select the Microsoft 365 Personal subscription you have and select “Manage”.
- Select “Unsubscribe”.
- View “Switch to a subscription that suits you better*” and select “Microsoft 365 Personal Classic”.*
- After following the instructions to complete your subscription. Your subscription will automatically renew to Classic when its existing subscription expires.
