Hi guys,

We are migrating/transitioning from Exchange 2010 to Exchange 2013 and we have the following set-up at the moment in our test environment.
- Exchange 2013 (3x Multi-role servers)
- Exchange 2010 (2x MBX and 2 HT/CAS running NLB)

Certificates should be correct on both servers with appropriate SAN names.

We would like to verify the configuration regarding the vdirs, especially related to ActiveSync and Outlook Anywhere, we did get owa/ecp to work without any trouble.

Exchange 2013 will proxy the connection towards Exchange 2010 if the mailbox still resides on the old environment and what we have learned is that we should have the following configuration?

Exchange 2013 (ActiveSync vdir)
- internalurl: mail.company.com
- externalurl: mail.company.com

Exchange 2013 (ActiveSync vdir)
- internalurl: mail.company.com
- externalurl: $null (to get the server to understand that it should proxy)

Exchange 2013 (rpc vdir)
- internalhostname: mail.company.com
- externalhostname: mail.company.com

Exchange 2010 (rpc vdir)
- internalhostname: mail.company.com
- externalhostname: mail.company.com

Do we have to do anything with the authentication of these vdirs or any other things we should know about?
Is it just Microsoft-Server-ActiveSync vdir that is special and we should set externalurl to $null?

Please advice!

Hi,

Based on my knowledge, if Exchange server 2013 is Internet facing and Exchange server 2010 is non-Internet facing, we can configure both internal and external URLs for Exchange server 2013 and internal URLs for Exchange server 2010. CAS 2013 will proxy request to CAS 2010.

Find a great blog for your reference:

Thx for your reply.

Everything is in the same site and the 2010 servers are internetfacing (running the various services as of now for the clients)

You just configure the same URLs for Exchange 2013, point DNS entries(including Autodiscover) to Exchange2013 and enable outlook anywhere. As suggested above it will Proxy to Exchange2010 if the mailbox is not in Exchange2013. I suggest you make Exchange2013 as interfacing and it will do the rest. Please check below to configure the URLs

Hi,

Agree with MAS. Any update?

 

Thanks

Don't forget to set the EWS url's too. Outlook clients need EWS for calendar free/busy information.
