This article describes update 4462111 for Microsoft Outlook 2016 that was released on March 10, 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:

  • Fixes an issue that causes the user selection for the hash algorithm not to persist.

  • Fixes an issue that causes crashes when users run rules on certain email messages.

  • Fixes an issue in which Outlook sometimes crashes when you view calendar sharing requests by having "Read all standard mail in plain text" turned on.

  • When you send a meeting request that contains attachments, the attachments may be duplicated in the calendar items. This issue occurs when Outlook runs against an Office 365 account in Online mode.

  • Fixes an issue that causes Outlook to use an excessive amount of CPU when you view the calendar window and resize the window to a narrower size.

  • Fixes an issue that causes some users to experience a crash.
