Hi Michael,

thank you for your response. My horde log shows

Oct 23 14:42:28 isogramm HORDE: [imp] Login success for test at domain.com ( to {imap://horde.server.de/} [pid 28966 on line 157 of "/var/www/horde/htdocs/horde-base/imp/lib/Auth.php"]

for about 4 times per second if I start outlook and while it trys to sync. Do you need a debug log? The webserver log is clear; there are no errors.

It appears like a normal FOLDERSYNC request and response, except for some reason the client either isn't receiving it completely, or there is some error being thrown that is causing non-wbxml data to be included in the output stream.

Does your horde log show anything? Web server error log? I can verify that connecting via OL2013 works as expected with a fresh install of the latest Webmail packages.
