[horde] Activesync not working but seems fine in logs?

[info at pcbase.eu]

Hi all,

I configured horde for activesync usage, but then I try to sync email,  
calendar and contacts, it just fails according to my phone.

This is the ActiveSync log:

I thought that it might be a webserver problem, but that wasn't right,  
because it just returns a 200 status:

[17/Jun/2011:19:08:38 +0200] "POST  
/Microsoft-Server-ActiveSync?Cmd=Sync&User=[MYUSER]&DeviceId=HTC942974c4d7bf04a7bd941aa283c5d&DeviceType=htcpyramid HTTP/1.1" 200 82 "-"  
"Android-EAS/4.0.2115272322.67241"

When I try to access the webportal I can browse my mail, contacts and  
calandar fine, but AS just won't work. Any ideas why?

Thanks!
