Hi,<br />
&nbsp;I have added new exchange 2010 Servers in a new AD site. We have exchange 2007 in the same domain but different site so we are planning to migrate all to the new exchange 2010.<br />
<br />
I run the following command from the exchange 2010 CAS to enabled the redirection for exchange 2007 mailboxes:<br />
<br />
Set-OWAVirtualDirectory EX2010CAS3\OWA* -Exchange2003URL https://legacy.domain.org/exchange<br />
<br />
the command run ok but testing &nbsp;OWA When I tried to open a mailbox in the same OWA Exchange 2010 form it complain with the error after enter the &nbsp;exchange 2007 mailbox account &quot;Outlook Web App isn't available. If the problem continues, please contact your helpdesk&quot; OWA with Mailboxes in 2010 are ok.<br />
<br />
I have running the same command before for other similar implementation wirh exchange 2007 and exchange 2010 and it works but not sure why this time seems that nothing happen.<br />
<br />
Any ideas?<br />
<br />
Thanks,<br />

OWA redirection from exchange 2010 to exchange 2007 does not work

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
