Hello folks...
In this post I will try to explain the differences between Basic and NTLM Authentication for Outlook Anywhere service.
Basic Authentication:
This method always requests the user to enter the user name and password when ever starting use Outlook Anywhere (not any more in Outlook 2010 and 2013), and it will send the credentials over internet in plain text ( not secure), that why you need to use it with SSL.
for outlook 2010 and 2013 clients, they can select Remember my credentials option to save their credentials, in this way outlook will not request for credentials again.
NTLM Authentication:
Also known as Integrated Windows Authentication, in this method outlook will use the current (cached) OS login credentials.
The credential exchanged between client and server in a hashed value insted of a plain text.
Although, its more advance but it may not works with some firewalls, you need to make sure that your firewall support this method before configure it.
Thanks.
