"Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later" error when you try to open the Out of Office Assistant in Outlook 2010

View products that this article applies to.

Symptoms

Consider the following scenario:
  • You configure the proxy server connection settings for Windows Internet Explorer.
  • You add the Client Access Server (CAS) servers to the proxy exceptions list in Windows Internet Explorer on a client computer.
  • You open a mailbox profile in Microsoft Outlook 2010 by using credentials that are different to the credentials that you used to log on to Windows.
  • You try to open the Out of Office Assistant in Outlook 2010.

In this situation, you receive the following error message:

Your Out of Office settings cannot be displayed, because the server is currently unavailable. Try again later.

Note You do not receive this error message in either of the following scenarios:
  • You log on to Windows by using the local user credentials.
  • You log on to Windows as a domain user, but you do not add the CAS servers to the proxy exceptions list in Windows Internet Explorer.

Cause

This problem occurs because the CAS server uses the credentials that you used to log on to Windows instead of the credentials that you used to log on to the mailbox in Outlook 2010. Because the Windows credentials do not match the mailbox credentials, the CAS server returns a "500" error code. However, the "500" error code is not an authentication error code. Therefore, no other authentication methods are tried.
