A Rollup Update has been released for Outlook 2016. This is a non-security update which contains the following documented improvements fixes.

    • The message size of saved or sent items is displayed as “0 B.”
    • The attachment icon isn’t displayed in the message list for items that have attachments.
  • Fixes an issue that causes the Peek view of Outlook Calendar to occasionally display incorrectly.
  • Addresses an issue that prevents users in the Saratov time zone (GMT+4) from opening a single instance in a meeting series.
  • Addresses an issue that causes Outlook to crash when a user forwards a message from which attachments have been removed.
  • Addresses an issue that causes the retention information bar to show items incorrectly in the Deleted Items folder as “expired.”
  • The Open this task button in the WORKFLOW TASK prompt is unresponsive for certain email messages.
    Outlook crashes when you try to mark messages as read from the Unread folder.
