Office 365 for home
You can install Office on your Mac or PC if you have a subscription to Office 365 Home, Personal, or University, or if someone has shared a subscription with you.
In order to install or reinstall Office, or manage your Office 365 subscription, you need to sign in with the Microsoft account that's associated with the version of Office you have. The following article will help you find the Microsoft account that you associated with Office.
You can renew Office 365 online through Microsoft, or buy another year of the subscription from a retail store.
If you're in the middle of your Office 365 trial, you can cancel your trial online before your trial period ends.
Office 365 Home can be shared with up to four people in your household. You and the people you share with can install Office desktop applications on up to 5 computers, which can be a combination of Macs and PCs, 5 tablets, and 5 smartphones. If you've used up all of your available installs and need to install on another computer, you can free one up by deactivating one of your existing installs. You can also stop sharing your subscription with someone.
Office 365 for business
If you can’t sync files between your computer and OneDrive for Business, it might be due to problems with the OneDrive for business sync client. We recommend you try the Next Generation Sync Client.
