If you have the most recent Office 365 update installed (version 16.0.6568.2025), your emails may get deleted from the server or you may receive duplicate emails in your inbox.

The Outlook team is aware of the problem and actively investigating the issues. We’ll update this post and KB 3145116 as more information becomes available.

For now, please try workaround steps provided in this article (KB 3145116):

  • Configuring your email account to use IMAP settings instead of POP3 (only if your email provider supports this).
    OR
  • Reverting to an earlier version of Office 2016 via uninstall of latest update.

IMPORTANT If you disabled the “Remove from server after <x> days” option in Outlook 2016 to fix the delete email issue you’re probably now getting duplicate emails in your inbox. To avoid both problems, please re-enable the “Remove from server” option and use one of the other workarounds listed in the KB article.

UPDATE 4/3/2016: From Microsoft,  “We have a fix for both POP3 bugs: duplicate emails and server-side mail deletion. The fix should roll out in the next couple of days, and once it’s available, we’ll let you know.

UPDATE 08/3/2016: From Microsoft, “We are in the process of rolling out an Office update now (version 16.0.6568.2036), which will fix the POP3 bugs”
