OutlookAnywhere SSL Offloading True vs False

Hi,

I am working in a lab where i have exchange 2010 and exchange 2013 (Multi Role) in coexistence environment. I tried to set Outlookanywhere by following command.

Set-OutlookAnywhere "AR3EX01\Rpc (Default Web Site)" -ExternalHostname mail.domain.com -ExternalClientsRequireSsl $true -InternalHostname mail.domain.com -InternalClientsRequireSsl $true –ExternalClientAuthenticationMethod NTLM –SSLOffloading $false

When I set –SSLOffloading $false then Exchange 2013 Users prompting password and even new user can not configure email profile because of password not accepting.

I set –SSLOffloading $True , there is no password prompt and proxy settings also perfect.

What is the logic behind this and what should be exact settings.

Regards

Usman
