Hey Guys

I need some help getting the correct Authentication methods for OWA coexistence between 2013 and 2010. I cant seem to find any documents which provide the right settings.

Thanks,

I was really hoping to get this question answered and thought it would be a simple search to get the info. but apparently I am unable to find a straight answer to my question. Might you know the answer?

Thanks,

This is for the 2010:

ClientAuthCleanupLevel        : High
InternalAuthenticationMethods : {Basic, Fba, Ntlm, WindowsIntegrated}
BasicAuthentication           : True
WindowsAuthentication         : True
DigestAuthentication          : False
FormsAuthentication           : True
LiveIdAuthentication          : False
AdfsAuthentication            : False
OAuthAuthentication           : False
ExternalAuthenticationMethods : {Fba}

2013:

So i noticed this lastnight: 

CAS4 - Good Server that works as expected: (Exch2010, SP3, RU7)

CAS1 - Bad Server that does not work: Exchange 2010 SP3 RU7

If you notice the one server (bad server) does not have Windows Auth Enabled, when i enable it exchange disables forms. If i try enabling all 3 at the same time it still disable forms. So i need to set the Auth a different way is that done via IIS?

Hi,

Please don't do any changes in IIS Manager, just run the following command in EMS to enable Integrated Windows authentication for CAS1:

Set-OwaVirtualDirectory -Identity "CAS1\owa (Default Web Site)" -WindowsAuthentication $True

Then run the following command to check the OWA configuration:

Get-OwaVirtualDirectory | fl identity,*auth*

Hi,

There are some articles about the Client Connectivity in an Exchange 2013 Coexistence Environment. Hope they are helpful to you:)
