November 5, 2019, update for Outlook 2016 (KB4484139)

This article describes update 4484139 for Microsoft Outlook 2016 that was released on November 5, 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 adds a PreferProvidedEmailInAutoDiscoverAuthPrompts registry key that enables Exchange administrators to specify whether users will be authenticated by using the configured account email or the user principal name (UPN) during AutoDiscover scenarios.

Registry key

Location: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover

Value Type: DWORD

Value name: PreferProvidedEmailInAutoDiscoverAuthPrompts

Value data:

  • 0: It's the default value. Outlook will use the UPN when it's available.

  • 1: If the value is set to 1, Outlook will ignore the UPN and just use the provided account email.

It also fixes the following issues:

  • Outlook doesn't show original URL on hover on an email message with more than 50 URLs.​

  • Fixes a memory leak when you use Outlook 2016.

  • When you save an email message to the Drafts folder after you change the sender in online mode, the sender name is changed to the LegacyExchangeDN value.

  • When you copy an attached email message from the preview pane, and then paste it in an inline reply, Outlook 2016 crashes.
