It seems that the problematic line is Date: Sun, 16 May 2016 19:19:42 0000 Where the last "0000" instead of the "2016" gets parsed as the year. That's a malformed Date field. The offset must be written as +0000, so the message is essentially broken. It could be handled more gracefully though. While this is not a Horde bug we can sanity check the date in the place where horde reads it, but the original headers are still sent to the client so this may or may not help OL be less of a PITA. See https://tools.ietf.org/html/rfc2822#page-14

The mail attached cause the sync of Outlook 2012 with the server to fail. There is no indication in Outlook 2012 that the sync has faild. Just no messages later than the arrival of the attached mail are loaded. Complete resync does not solve the issue this mail caused. Mails until the arrival of the attached mail will be reloaded and then it stops. In use is ActiveSync 2.33.1. It seems to be an issue with the date as the date shown in Horde Webmail is the year 0. Removing this mail from the inbox of the user re-enables sync with Outlook 2012. A paired iPhone to the same account at the same time did not encounter any issues.
