Microsoft has released the January 2021 non-security Microsoft Office updates with fixes for known issues impacting Windows Installer (MSI) 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.

The KB4493166 update addresses an issue causing users to experience recurrent crashes while using Outlook 2016.

This update also fixes issues blocking justification texts when overriding a policy and causing the headers of Chinese messages to become unreadable when replying to or forwarding emails.

Although these are issued as non-security updates, this month Microsoft has also issued KB4484509 which comes with Access 2016 reliability improvements for Visual Basic for Applications (VBA) projects, and KB4493157 to improve Visual Basic for Applications (VBA) projects' signature scheme.
