Hello,

On my exchange 2003 sp2 organization, i add yesterday a new 2010 sp1 server (Cas-Hub-Mbx) in the internet-facing site.

Activesync works well with the 2010 mailboxes but i've lost connectivity between iphones and 2003 mailboxes on the same site.

I've no FE2003 in the organization, just one BE2003 on the site (also two more BE2003 on other sites equaling children domains).

I've given a SAN cert to my BE2003 (legacy.dom.com and server2003.dom.com), a San Cert to the CAS2010 (mail.dom.com, server2010.dom.com, autodiscover.dom.com).

Exchange2003url has been set to https://legacy.dom.com/exchange.

Integrated windows authentication is activated on BE2003 (just one, all iphone users have their mailbox on this internet-facing 2003.

What's the configuration error ?

The BE2003 has FBA activated, with no compression, and SSL requested on owa, microsoft-activesync, oma and exchange-oma vdirectories.

On exchange 2003 general parameters, activesync and direct push are activated, like OMA.

Must i deactivate FBA, SSL and/or OMA on the BE2003 server ?

Help required ...

Thanks
