You will need to set all of the URLs stated in the article you reference, not just the URLs for OWA.<br />
<br />

<br />
Personally, I would run them from the Exchange Management Shell on the Exchange 2013 server.<br />
<br />
<br />

Create a certificate request from the Exchange 2013 server that includes the names (except internal/non-routable names) from the existing SSL certificate as well as adding legacy.domain.com. &nbsp;Once you complete the certificate on the Exchange 2013 server (after purchase and assigning services), export the cert from 2013, import into 2007, assign services (IIS and SMTP), and finally run an IISRESET. &nbsp;Lastly, check the status of the certificate from <a href="https://www.digicert.com/help/" rel="ugc">https://www.digicert.com/help/</a>.

hi Todd,<br />
<br />
nice haering from you,<br />
<br />
so all legacy urls and new urls of virtual directories to be run from EMS of exchange 2013<br />
<br />
and the certificates will need to cover those legacy urls' s as well?
</div>


<div>
If you take a close look at the commands in the article you reference, you will find that a specific command will run against a specific server.<br />
<br />
Maybe a slight modification to the commands will provide clarity...<br />
<br />
Set-OwaVirtualDirectory –Identity “<b>ex2013servername</b>\owa (Default Web Site)” –InternalUrl https://webmail.domain.com/owa&nbsp;–ExternalURL https://webmail.domain.com/owa<br />
<br />
Set-OwaVirtualDirectory –Identity “<b>ex2007servername</b>\owa (Default Web Site)” –InternalUrl https://legacy.domain.com/owa&nbsp;–ExternalURL https://legacy.domain.com/owa<br />
<br />
With regard to the certificate, if the existing certificate includes the following names...<br />
<br />

<ul>
<li>mail.domain.com</li>
<li>autodiscover.domain.com</li>
<li>servername1.domain.local</li>
<li>servername2.domain.local</li>
<li>servername3.domain.local</li>
</ul>
<br />
Then the names in the new certificate should resemble something like this...<br />
<br />

<ul>
<li>mail.domain.com</li>
<li>autodiscover.domain.com</li>
<li>legacy.domain.com</li>
</ul>
<br />
See how the legacy name is added and the old internal FQDN names are removed?<br />
<br />
Hope that helps.

<div>
is below correct?<br />
<br />
Unfortunately Exchange 2013 will only proxy OWA for 2010 and not 2007, which is why the new legacy domain is required.
