Dear All,

I am facing issue regarding basic authentication in exchange 2013 I run all the command and from Server setting I set the outlook anywhere on Basic Authentication but when I configure outlook client after successfully run the wizard the setting of outlook in Exchange proxy setting its show NTLM. I run all the below commands and done with the srver setting but outlook will configured only on NTLM. Externally and Internally both are same through autodiscover.

Set-OutlookAnywhere -Identity: "servername\rpc (Default Web Site)" -ExternalClientAuthenticationMethod Basic

Set-OutlookAnywhere -Identity "servername\rpc (Default Web Site)" -SSLOffloading $false

Set-OutlookAnywhere -Identity "servername\rpc (Default Web Site)" -IISAuthenticationMethods Basic

Set-OutlookAnywhere -Identity "servername\rpc (Default Web Site)" -IISAuthenticationMethods Basic,NTLM

I just need to confrim that there is no more Basic Authentication support in Exchange 2013 or is there any work ar

Hi Danish,

Basic authentication is supported on Exchange 2013, you can use the following cmdlet to set it.

Set-OutlookAnywhere -Identity "servername\Rpc (Default Web Site)" -InternalClientAuthenticationMethod Basic

What's more, it is recommended to set the IISAuthenticationMethods to: {Basic, Ntlm, Negotiate}.

For your reference:

Set-OutlookAnywhere
