Hi,

i only have 1 exchange server and OWA configured for SSL.. Will i have
problems using the active sync to sync my mails in those cellphone with
active sync capabilites? Do i need to create another virtual directory for
the active sync?

Yes, you'll need to create a separate virtual directory and create a
registry value as explained in the following KBA:

Hi,
Hope u could spare little time to solve my puzzle.

1) But why the it cannot use the same directories as OWA? Is that becos of
SSL?
If yes, why can't use the same SSL?

2) Can the oma or active sync use SSL? looking at the technote, it says
disabled SSL. But our cell phone with activesync, there is an option for SSL.

Thanks!

The KBA explains the cause - scroll down and read the "More Information"
section:

To access the contents of a user's mailbox in Exchange Server 2003, the
Microsoft-Server-ActiveSync and the Outlook Mobile Access virtual
directories make an explicit DAV logon to the Exchange virtual directory.
The call is similar to the following:
http://netbios_name_of_mailbox_server/exchange/mailbox_alias
The Microsoft-Server-ActiveSync and Outlook Mobile Access virtual
directories cannot access the contents of the user's mailbox if the Exchange
virtual directory is configured to require SSL. The
Microsoft-Server-ActiveSync and Outlook Mobile Access virtual directories
only try to connect with the Exchange virtual directory over TCP port 80
(HTTP), not over TCP Port 443 (HTTPS).

The workaround mentioned in the KBA works and it is quite simple to
implement. You need to create a virtual directory and a registry value to
point to the virtual directory. This will let you use SSL on your OWA/
/Exchange directory, and still make OMA and ActiveSync work.
