WAF-Exchange 2007-ActiveSync --> No signature found

Odi
i have used the KB article from Sophos "Configuring UTM firewall for Exchange.pdf" to config my WAF for Exchange 2007.

We only need ActiveSync for our iphone-Users. Therefore i've configured ActiveSync only.

Unfortunately this will not work. 
If i'm browsing the address with the Browser i'll get: No signature found

If i switch off URL Hardening in the Exception List, everything is working fine.

I noticed that the requested url from the iphone is something like:
activesync.acme.com/Microsoft-Server-ActiveSync&DeviceId=1234abcd......

in the Exception List the entry is:
/Microsoft-Server-ActiveSync/*
which it seems not to match with:
/Microsoft-Server-ActiveSync?User....

do someone know the korrect expression?

regards
Tibor

    Yes...leave the slash behind /Microsoft-Server-ActiveSync* away.

    Sorry for short answers and typos. was written on mobile using astaro.org app.

    yes, i thought similar.

    i've changed the exception expression but now
    the last mail is downloaded each time i check the mailbox and the body of the mails can not be downloaded.

    it looks like it's working now.

    i've reconfigured the external address on the CAS server and reconfigured the settings on the UTM.

    thx
