Microsoft has released the January 2021 non-security Microsoft Office updates with fixes for known issues impacting Windows Installer editions of Office 2016 products.
Microsoft has also released non-security updates in Current Channel releases for Microsoft 365 Apps to address Excel crashes and Outlook hangs.
This month's Office non-security updates can be manually installed from the Download Center or automatically by using the Microsoft Update service.
The updates only apply to perpetual versions of Office using Microsoft Installer-based installers and do not apply to Microsoft 365 Apps.
After applying some of this month's Microsoft Office updates you may also be requested to reboot your computer.
Depending on the Office update you're using, you may also have to apply other updates to fully address issues on your device.
