Microsoft Outlook keeps asking for credentials

Version 1

    Problem

    Consider the following scenario:
    • Microsoft Outlook is used in a RES ONE Workspace managed environment.
    • E-mail Settings are configured to use AutoDiscover.
    • A proxy server is used to connect to the internet.
    In this scenario Microsoft Outlook keeps asking for credentials when the mailbox is configured.

     

    Cause

    The Microsoft Exchange AutoDiscover URL is not included in the Microsoft Internet Explorer proxy exclusion list.
    As a result the AutoDiscover process fails.


     

    Solution

    Add the Microsoft Exchange AutoDiscover URL to the Microsoft Internet Explorer proxy exclusion list.
