Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello, thank you for reaching out to Microsoft Q&A.
If you prefer not to use Copilot AI features, such as Designer or Copilot, in Office 365 apps, you can switch back to the Classic 365 plan. This plan includes only the standard Office apps and will remain at the same cost you’ve previously paid.
To switch to classic, sign in with your Microsoft account here-
https://account.microsoft.com/services
- Select your Office 365 subscription, and click Manage subscription.
- Then, click Cancel subscription.
- You should have the option to switch back to the classic plan.
