Be aware that the update on the 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

  • Parses nested rule collections in Outlook add-in manifests.
  • Adds the ability to select and interact with multiple attachments in Outlook 2016.
  • Fixes the following issues:
    • When you try to send a meeting request that has an attachment and the save operation is called by the ItemSend event in Outlook 2016, you receive the following error message:
      The operation failed.
    • When you open an email message in Outlook 2016, you receive the Access Denied error message. This issue occurs because an incorrect cached token is used to access email messages if you open different email messages within 60 seconds.
    • When you try to open or save an attachment that has a long file name in an email message in Outlook 2016, Outlook 2016 crashes.
