Hi Miller,

Microsoft found out that CAS plays a big part of this issue. They mentioned that there is a possibility that you might have different credentials used between your windows logon and mailbox credentials. That is, CAS is responsible for opening up your mailbox using credentials acquired from windows. So when CAS and Mailbox credentials do not match this will return an authentication error and hence no other authentication will be made. For now, you may try to apply MS’s hotfix. After which you need to enable this hotfix from your registry. Follow steps below.

After you apply the hotfix package, follow these steps to enable the hotfix:

1. Click Start, click Run, type regedit in the Open box, and then click OK.

2. Locate and then click the following registry subkey: 

HKEY_CURRENT_USERSoftwareMicrosoftOffice14.0OutlookSecurity

3. On the Edit menu, point to New, and then click DWORD (32-bit) Value.

4. Type WinhttpAuth, and then press ENTER.

5. In the Details pane, right-click WinhttpAuth, and then click Modify.

6. In the Value data box, type 1, and then click OK.

7. Exit Registry Editor.
