If you let your subscription expire you will still have access to your saved items on OneDrive. If you have reached your free OneDrive 7 gigabyte (GB) storage limit, you won't be able to add or edit documents until you reduce your OneDrive storage below your quota. However, you can access your documents saved on OneDrive and download them at any time.
30 days prior to expiration, you will receive an email reminder from Microsoft telling you to renew your subscription. Then 15 days prior to expiration, a reminder will appear in the applications, reminding you that it's time to renew. At expiration you will see a "Subscription Expired" notification in the applications.
You can renew your Office 365 subscription any time by purchasing another Product Key for Office 365 from us. Just be sure that you activate the Product Key with the same Microsoft account for your existing Office 365 subscription. Once your subscription expires you can click the onscreen reminder in any of the Office applications to either purchase a new subscription direct from Microsoft, or enter in a new Product Key that you have already purchased.
No. If you activate multiple years of subscription at once, your expiration date extends but the other benefits do not stack. So, if you activate two years at once, you'll receive 2 years of Office 365, but you'll still only receive the 1TB of OneDrive and 60 Skype world minutes/month. You can have a maximum of 5 years of Office 365 Home active on one Microsoft account.
