Additional Exchange 2007 Support for EV
The fact that you have to open the EV server to the outside world to get Archive Explorer and Vault Search to work with Exchange 2007 OWA is KILLING us on Exchange migrations. I can not sell every client ISA server or an F5 (even though I would like to).
This problem has also caused us numerous headaches when deploying Outlook Anywhere with Exchange 2007 for client that are using EV.
We have also received numerous complaints that the shortcuts in the preview pane no longer work in OWA because they do not contain an externally accessible FQDN and the extensions are no longer able to proxy these through based on the hostname.
I realize OWA is significantly different in Exchange 2007 than in 2003 but for that reason people are using it more heavily and rely on access to Enterprise Vault funcationality through it.
