Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Brad M
Hi, I'm Karl and will be happy to help you today.
Not entirely clear about what you mean by "I have installed the Microsoft 365 app online versio". There is nothing to install to use the online Office apps.
To install the Microsoft 365 desktop Office apps, you need to log into the Microsoft Account associated with your Microsoft 365 Personal or Family subscription using the following link
https://account.microsoft.com/services
If you purchased a Microsoft 365 Basic subscription, that does not include the desktop apps. It only includes the Office online apps. Is it possible that this is what you are referring to?
I look forward to your response so we can proceed further.
