Outlook 2010 prompts for PW

We have random users all who get this password prompt for Outlook 2010.  We use Exchange 2010 DAG config with a Casarray.  Ive read numerous forum discussions on this matter but Ive recently checked my Outlook Anywhere Auth settings and see they are set to BASIC and not NTLM.  It would seem that I should change them to NTLM.  Now my understanding is Basic asks for authentication not assuming the user has authenticated by logging into he domain so it somewhat explains why users get prompted for their Outlook pw however it doesnt explain why it is not happening to every user and just some at different times. Does anyone know why it happens for some but not all as thats what management will ask me.

is my best option to switch to NTLM? or is there something else causing this and if I am to switch to NTLm is it as simple as checking the NTLM selecting and hitting apply or is there more to it?


Thanks

Are you talking about internal or external users?
Internal users shouldn't be using Outlook Anywhere at all, that only kicks in if the client cannot connect to the Exchange server using TCP/IP.

Have you confirmed that it is failing over to Outlook Anywhere? If it is, then you need to investigate why, rather than deal with the symptoms.

In the main, I usually try to start with Outlook Anywhere using NTLM, as it allows pass through authentication for domain clients. However it can get broken by some firewalls, so you often have to fall back to Basic to get it to work correctly.
