View products that this article applies to.

This article describes update 4484212 for Microsoft Outlook 2016 that was released on January 7, 2020.

Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2016. It doesn't apply to the Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home (see What version of Office am I using?).

Improvements and fixes

This update contains the following fixes:
  • When an email message that has a signed email message as an attachment is also signed, Outlook breaks the digital signature of the attached message.
  • Memory leaks occur when toast notifications are enabled.
  • When the display size is scaled to more than 100 percent in Windows 10, mailbox elements are not displayed correctly in the additional mailboxes list box on the Advanced tab in Microsoft Exchange dialog box. Additionally, it is difficult to recognize them.
  • When the weather service isn't available, Outlook doesn't stop making service calls after it receives an HTTP 404 error. This causes a heavy network load.
