Exchange 2013 & Exchange 2007: Mixed URLs and Auth
When we do a migration and configuration the urls and authentication becomes the toughest part to decide which changes as per the organization requirements. Most of the authentication varies from the org to org.
Here I am trying to explain the configuration I have practiced with Exchange 2007 and 2013 co-existence. This should work with most of the environments. I have configured the same in many migrations and it has worked every single time.
| Internal URL | Exchange 2007 | Exchange 2013 |
| OWA | https://CASFQDN/owa | https://mail.domain.com/owa |
| EWS | https://CASFQDN/EWS/Exchange.aspx | https://mail.domain.com/EWS/Exchange.aspx |
| Outlook Anywhere | https://mail.domain.com | https://mail.domain.com |
| ActiveSync | https://CASFQDN/Microsoft-server-Activesync | https://mail.domain.com/Microsoft-server-Activesync |
| External URL | Exchange 2007 | Exchange 2013 |
| OWA | https://Legacy.Domain.com/owa | https://mail.domain.com/owa |
| EWS | https://Legacy.Domain.com/EWS/Exchange.aspx | https://mail.domain.com/EWS/Exchange.aspx |
| Outlook Anywhere | https://mail.domain.com | https://mail.domain.com |
| ActiveSync | https://mail.domain.com/Microsoft-server-Activesync | https://mail.domain.com/Microsoft-server-Activesync |
| Internal Auth | Exchange 2007 | Exchange 2013 |
| OWA | Basic, Fba | Basic, Fba |
| EWS | NTLM, WindowsIntegrated | NTLM, WindowsIntegrated |
| Outlook Anywhere | Basic, IISAuthenticationMethods NTLM, Basic | NTLM IISAuthenticationMethods NTLM |
| ActiveSync | BasicAuthEnabled: True; WindowsAuthEnabled:True | BasicAuthEnabled: True; WindowsAuthEnabled:True |
| External Auth | Exchange 2007 | Exchange 2013 |
| OWA | Basic, Fba | Fba |
| EWS | NTLM, WindowsIntegrated | NTLM, WindowsIntegrated |
| Outlook Anywhere | Basic, IISAuthenticationMethods NTLM, Basic | Basic, IISAuthenticationMethods NTLM |
| ActiveSync | BasicAuthEnabled: True; WindowsAuthEnabled:True | BasicAuthEnabled: True; WindowsAuthEnabled:True |

Hi,
This is really good one .. Do you have similar blog for Exchange 2010 and 2013 URLs & Auth.
February 5th, 2015 at 11:48 pm
2010 and 2013 share the same urls so my migration blog works very well because 2010 accepts proxy. 2007 needs redirection for owa and EWS.

Prabhat,
I need to know what correct auth types are for 2013/2010 coexistence? do you have a table like the one above?
Thanks,
Robert

Ok. So for Exchange 2013: it would be Basic? (Not forms)? and for the Exchange 2010 Cas Servers it would be NTLM? Can you explain a little more please?
Thanks,
Robert

Migration blog mostly covers it. Are you facing any issue?
