Improvements and fixes

  • Translates some terms in multiple languages to make sure that the meaning is accurate.
  • When Outlook add-ins call the SetBody and GetBody functions, HTML inline attachment images will be set and returned correctly. It also makes this function more reliable generally.
  • Updates the translation in the Propose New Time dialog box of a meeting item in Japanese in Outlook 2016.
  • Fixes the following issues:
    • If you select the plus signal ("+") to expand a distribution list in the To field of a meeting request in Outlook 2016, Outlook 2016 may crash. This issue occurs if Outlook 2016 has a third-party add-in installed.
    • When you open Outlook 2016 that has more than 30 calendars in a calendar view in a Citrix environment, Outlook 2016 freezes. To fix this issue, see KB3141476 for more information.
    • Assume that you right-click an email message from a distribution list and select to create a rule for email messages from the distribution list. When you receive an email message from a member of the distribution list, the rule does not work as expected.
    • Fixes several email, calendar and contacts sync issues experienced by some users who have upgraded Outlook.com accounts.
    • When you send RTF email messages that have attachments in Outlook 2016, Outlook 2016 may crash if you have an add-in that deletes and adds attachments back on sending.
    • The Download Public Folder Favorites setting does not work in Outlook 2016.
    • When you open an instance of a recurring meeting in Online mode in Outlook 2016, Outlook 2016 may freeze.
