This article describes update 4464585 for Microsoft Outlook 2016 that was released on June 4, 2019.

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 improvement and fixes:

  • Improves translations for multiple languages versions of Outlook 2016.Note To enable this improvement, you also need to install KB 4464581 together with this update.

  • When the mailbox is full, if you try to restore an email message from the Recover Deleted Items dialog box, you will receive an error message and the item will be deleted permanently.

  • When your delegate changes a meeting date on your behalf, the updated meeting date isn’t displayed on your calendar.

  • This update enables Outlook 2016 to send requests by default during Need Password. If you need to block this behavior, set the value of the AllowRequestsInNeedPasswordBehavior registry key to 0 in the HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Security location. For more information, see KB4464517.

  • If there are a few rows of attachments in a message, the click behavior on attachments such as double-click, single-click or right-click doesn’t work as expected in certain cases.
