<h2 class="wp-block-heading"><strong>Symptoms</strong></h2>



<p>After you migrate Exchange 2003 to Exchange 2010, some outlook client users keep getting prompted to enter their credentials again.</p>



<h2 class="wp-block-heading"><strong>Cause</strong></h2>



<p>The problem might be related to the authentication method used on Outlook Anywhere. (Basic Authentication). </p>



<p>The recommended approach is to use NTLM authentication which keeps credentials cached. </p>
