UTM 9.3 Outlook disconnect problem

PhilippeTAVERNE
Hi,
We were using Sophos UTM9   version 9.209-8  on a virtual machine with 3 Go of memory. The proxy is using for accessing to the Internet , for hosted applications like Exchange Online with Outlook 2007 .
Since I have updated the version of UTM for 9.302-2 , I am facing of performance problem and Outlook 2007 loses connection and reconnect many time per hour. I have noticed that the using swap on server increases abnormally and that Secure Web statistics are no more available.
I rolled back to version 9.209-8 and the the Oulook connexion is now stable. Any Help will be appreciate.
Thanks

    Hello SmallAdmin,
    For my case,  I am configured as standard mode  with URL filtering only  setting for HTTPS traffic.  Indeed, disconnection appears only with https traffic


    Out biggest problem seems to be the downgrade now. Sophos just informed us, that it is unsupported and we would have to completely wipe the appliance, re-install 9.2 from ISO and upload an old configuration backup. Since we can't export and reimport all the changes we made since December 2014 this is a terrible mess...
