    Default ActiveSync after upgrade to iOS5 stops working


    I have Open-Xchange Server Edition and OXtender for Business Mobility. In the past, there was no problem with synchronization of the contacts, calendar and todo items ti my iPhone 4. Two days ago I upgraded my iPhone's firmware to iOS5 - and synchronization doesn't work any more.

    Regards Andreas

    Default Error message

    Don't know if error is caused by the upgrade of my iPhone to iOS5 or because I applied the latest patch to OX.

    Critical error seems to be:
    Request to server denied for session: 9272e067081e4d2cb743ddb39365fbca. Client login IP changed from 217.86.xxx.166 to 178.63.yy.199.
    The first IP is the address of my iPhone, the second is the IP address of the ox server.

    Here is the error messsage in /var/log/open-xchange/open-xchange.log.0

    Default solved

    I solved the problem inserting the public IP address of the ox server in /opt/open-xchange/etc/groupware/noipcheck.cnf

    A more secure way is to let the EAS/USM synchronization use localhost, if this is not a distributed system. See here. You can remove the public IP address then from noipcheck.cnf
