Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello, good day and thanks for your question. Sorry to know about this and I understand that you have a Macbook that is running on macOS Monterey 12.7.6 and you are looking into installing Microsoft 365 on it but you are also asking for a refund.
Please the below link and look for version 16.88 or 16.89.1 which is the ones that is compatible for the macOS that is running on your device and let me know how it goes.
