Question Horde with EAS - notes not synced on Outlook

[onki]

Hi,

my Horde with EAS is working nicely since some months now. Mails, Contacts and the calandar is synced without any problems. Only my notes do not show up in Outlook (2013).
Is notes syncing not supported by the current Horde EAS Version?
My Android Tasks&Notes App works with my Horde EAS.
I am using Horde 5.2.6 / Notes 4.2.6 and I am a bit afraid updating through Horde since last time I did that I had to reinstall horde through Plesk.

Best regards
Onki
