On the off chance that you introduced Office setup on a PC as a feature of your Office 365 for business membership, and your association changes to an alternate Office 365 for strategy for success, you may need to introduce the form of Office that accompanies your new arrangement.
Office tells you this by showing the accompanying message in Office in 1-3 days after your arrangement changes:
“Account Notice. Your Office 365 subscription has a pending change. To keep using your applications without interruption, please sign in now.”
“Update required. Your Office 365 subscription has a pending change. Please apply the change now to keep using your applications.”
If you are using Office 2016:
When you open Office and see the Account Notice dialog box, click Update and sign in, if prompted.
Office will download updates and complete the conversion in the background, even if Office isn’t running. Your old version of Office will be uninstalled as part of this process.
If you are using Office 2013:
Use Control Panel to uninstall Office, as described in Uninstall Office 2013, Office 2016, or Office 365 from a Windows computer.
After Office is uninstalled, sign in to Office 365 to install Office. If you need help, see Install Office on your PC or Mac.
