Hi,

Recently deployed an Exchange 2013 SP1 server into our existing 2010 SP3 organisation.

I've set the Silent redirect option on both CAS servers

Set-OWAVirtualDirectory -Identity "CAS2010\owa (Default Web Site)" -CrossSiteRedirectType Silent

Set-OWAVirtualDirectory -Identity "CAS2013\owa (Default Web Site)" -CrossSiteRedirectType Silent

Problem is that the silent redirect doesn't work if you go to CAS2010 URL and login you get the Redirection splash page where you have to click the link to the CAS2013 URL and login again. 

If you go to the CAS2013 URL and login to a mailbox that resides on the 2010 box it silently redirects you.

I have the same authentication settings on both Virtual Directories

Any ideas?

Hi,

You need to have a DNS record for OLD OWA with the name of e.g. legacy.domain.com/owa and set up redirection in CAS.

Thanks Riaz,

So I have CAS2010.domain.com and CAS2013.domain.com in DNS

What do you mean regarding redirection? Redirect in IIS for OWA on CAS2010 and point it to CAS2013? 

Hi Dave,

Tey following URL to setup OWA redirection.

Kindly mark this as answer if it fulfill your requiremetns.

Hi,

According to your description, the redirection from Exchange 2010 to Exchange 2013 has to be completed manually even though you have set the property CrossSiteRedirectType. If I misunderstand your meaning, please feel free to let me know.

If yes, there is something wrong with the Exchange 2010 configuration.
Lets firstly double check the values of the following properties:
Get-owavirtualdirectory |fl Identity, CrossSiteRedirectType, FormsAuthentication, BasicAuthentication

If you have any question, please feel free to let me know.
Thanks,

 

Hi Angela,

Here are the results

CrossSiteRedirectType : Silent
FormsAuthentication   : True
BasicAuthentication   : True
