I have the same problem with my Sony Ericson S700i. Previous I had no problem
with synchronisation with Outlook 2003 via billionton USB blue tooth stick.
Now I get the message not valid OBEX response to request and the
synchronisation fails.
What is OBEX response and what can I do

Do you get any error messages in your sync software?

I was previously able to synchonise my outlook calendar to my mobile phone,
nokia 6600. Suddenly i'm able to. Have spoken to nokia & they were not
able
to find any problem with the phone.
