In addition to KB3114409 which is not currently available, several other updates were released this week. Office 365 subscribers should receive the updates automatically sometime over the next few weeks, or you can check for updates in File, Office account, Check for Updates.
There were two updates for Outlook 2016. December 8, 2015, update for Outlook 2016 (KB3101550) fixes stability and other issues with data loss prevention (DLP) policies.
December 8, 2015, update for Outlook 2016 (KB3114387) fixes a MAPI over HTTP issue that causes repeated reconnection attempts. It also fixes a problem where Outlook crashes under certain circumstances when you use a screen reader. This update also addresses performance and stability problems.
Both Outlook 2013 and 2010 have one update available, however, the Outlook 2010 update is no longer available and will be replaced by an updated version. In addition to adding the option to prevent Outlook from running in Safe mode, it also addresses a handful of other issues, including the MAPI over HTTP issue that also affects Outlook 2016. Other problems that are fixed is one where multiple attachments are sorted differently if they contain Unicode character in the filename and the filenames may be swapped with other attachments. Also, the autocomplete cache doesn't work as expected when you send a message programmatically and an appointment that spans 2 days but is less than 24 hours long, appears on the calendar as two appointments.
The December 8, 2015, update for Outlook 2013 (KB3114349) adds support for Outlook apps that use Mail Apps API 1.3, fixes the problem that caused Outlook to take "forever" to configure an account using autodiscover, and also fixes the issue with update 3101488 that caused Outlook to crash. It also reduced the excessive network traffic during autodiscover and fixes a problem where the "Delegate can see my private items" setting for a delegate is lost.
It also addresses the following issues:
- Outlook may crash when its resolving addresses in the autocomplete cache.
- When you forward an email message that has the reading pane disabled, the recipients of the email message aren't displayed in the body text.
- When you try to delete items from public folders, you receive an error message: Changes made to the item were lost due to a reconnect with the server.
Custom add-ins use cached access tokens instead of tokens that are retrieved from the Exchange Web Service (EWS).
- The Inbox doesn't synchronize and the mailbox is renamed as an archive mailbox or an archive mailbox is renamed as your mailbox. You may see a duplicate view of your mailbox when you expand the archive mailbox.
- Microsoft narrator can't read the number of unread email messages in an email folder.
- These problems are fixed for users with IMAP accounts: Items are moved to a renamed folder; unable to import items if the folders have certain characters in their name.
