Offline Access 6.6 client with Exchange 2010 combination not in Compatibility Guide

Hi,

I've deployed a new ES1 6.5 installation in an Exchange 2010 environment.

Customer, as we suggested, wanted to deploy OA on their pcs client.

Standard email client used is Ms Outlook 2007 so no OA compatibility problems.

We did some test and everything works fine.

Just today reading the last ES1 compatibility  guide version 300-008-041 A10 at pag. 21 reguarding Oa 6.6 compatibility I notice that as Exchange server only version 2003 and 2007 are reported.

I'm a bit surprise because OA works closly with Outlook and ES1, so why it should be not compatible with Exchange 2010 ?

Customer is using it without problems at all.

Does anyone in EMC could confirm if OA6.6  could be used or not with Exchange 2010 ? If not why ?

Is anyone's customer using OA 6.6 within an  Exchange 2010 environment ?

Does anyone have problem using OA with Exchange 2010 ?

Thank you

Bye

Andrea
