Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello, Eeezzzma
I'm glad to hear back from you.
I understand that you have already performed the OneDrive sync, but the issue still persists.
Since Co-Pilot can only be used in the Excel preview version, may I ask if you are currently using the Excel preview version? If not, please upgrade to the preview version.
If you are already using the preview version, in order to assist you better, please provide the version number.
Thank you for your understanding and patience.
With best regards
