Hello,

We are deploying a fresh Exchange 2013 organisation as a Hybrid model.  We will deploy as a single Office 365 tenant in Europe, and a single Exchange organisation. Some countries that cannot consume the Office 365 /Exchange online from Europe (perhaps for legal / compliance / performance reasons) will have a local Exchange deployment in country.

We have deployed a pair of Exchange hybrid servers to our central European location, and have setup dns to point to these servers for autodiscovery.company.com and webmail.company.com

For those users which have a mailbox in country, we want them to be redirected to the local CAS server, we do NOT want them to use the European Hybrid Exchange server as a CAS and proxy to the in country mailbox server (which is far away, high latency).

How can we control this and ensure our users get a CAS redirection to the correct local Exchange CAS?

Thanks

Hi Simon,

If you want to deploy proxy and redirection between AD site, we need to configure ExternalURL property on relevant virtual directory.
Meanwhile, we need register relevant DNS record and SSL certificate.
More details about Proxying and Redirection, for your reference: https://technet.microsoft.com/en-us/library/bb310763(v=exchg.141).aspx

Thanks Allen for the link, although it refers to Exchange 2010, so I was not sure how much of it refers to Exchange 2013 ?

I did in the end find this blog link that seems to address the point : on Proxy and redirection for Exchange 2013:
