Failing to get outlook 2007 to work with Exchange 2013

Dear Experts,

Anyone who has archived Exchange 2013. Can you please share your experiences. We are having trouble getting the outlook to talk to Exchange 2013.

Here is our environment -

EV 10.0.4 on widows 2008 R2

EV server has Outlook 2007 with SP3(The hotfix mentioned inthe documentation does not work but th level of binary version is higher than the one in the hotfix i.e.) installed

Its a mixed Exchange environment with 2010 and 2013 where migration is going on from 2010 to 2013. There are mailboxes on 2010 and 2013 both.

These are the hotfixes installed for outlook on EV server

We are trying to find out from MS but still no luck.

Your kind advises are highly appreciated.
