Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Lucia,
Thanks for posting in the community.
For your first concern, your account should be assigned subscription from the page or assigned by your organization admin. If your subscription is assigned by your organization admin, you could contact your admin and reassign the subscription to your account again.
For your second concern, it is not related to your personal account. When the subscription is expired and you have renewed the subscription, you could sign your account in the Office application to reactivate it. To confirm whether your account has the subscription, please access https://portal.office.com/account/?ref=MeControl#subscriptions, click Subscription and check whether you have the service “The latest desktop version of Office”.
For your third concern, if you haven’t renewed the subscription for the school account, data that is associated with that account is held for 30 days. After the 30-day grace period, the data is deleted and can't be recovered. If your files are stored online (OneDrive or SharePoint), you could access your OneDrive and manually transfer the files to your personal OneDrive or local.
For your fourth concern, for Office for Web, it is free for everyone. For Office applications, you cannot use them unless you use the account with subscription to activate Office. For OneDrive service (education), you need to have a related license.
If you have any concerns, please feel free and come back to share with us. We are willing to help you.
Regards,
George
