This article describes update KB3115101 for Microsoft Outlook 2016, which was released on May 3, 2016. This update has a prerequisite.

Be aware that the update on 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. (How to determine?)

Improvements and fixes

  • Adds Defenders of Ukraine Day to the Outlook holiday list for Ukraine in Outlook 2016.

  • Translates the Defenders of Ukraine Day┬áinto the MSI-supported UI languages.

  • Updates some translations for some features in Outlook 2016 in multiple languages to make sure that the meaning is accurate.

  • Fixes the following issues:

    • When you try to create a new profile in cached mode in Outlook 2016, you receive the following error message if the .ost file name contains an MS-DOS device driver name:

      Cannot open your default e-mail folders. Unknown Error.

      For the list of default device driver names, see the "MORE INFORMATION" section in article KB74496.

    • Online archive and public folders may disappear for a profile in Outlook 2016.

    • Assume that Outlook 2016 connects to an Exchange server in an intranet by using the MAPI over HTTP transport protocol. If you open the Connection Status dialog box, the Authn column displays Error* but not AutoLogon*.

    • Time window settings in the Sync Slider window do not match those available in the Outlook 2016 Administrative Template.

    • Outlook 2016 ignores the non-policy SyncWindowSetting key if the disk size is smaller than 64 GB.

      Note See KB3115009 for more information.

    • Outlook 2016 immediately deletes or duplicates email messages for POP3 accounts regardless of email settings.
