Error MAPI. User is not authenticated (4224460)

WebThe Exchange Utility appears to process mailboxes and unstub messages but the messages are unchanged in Outlook. When investigating further, the following error is logged:

The Exchange Utility is not logging into the Archive Manager defaultinstance due to the authentication type being configured incorrectly either in IIS or in the web.config of the Archive Manager site.

Only one authentication method can be selected. If both Windows and Forms is enabled then you must decide which you want to use and set them in two places.

IIS Manager

• Open IIS manager and select the DefaultInstance site underneath the Archive Manager site.
• Check the authentication settings for the DefaultInstance and ensure only one method is enabled (either Anonymous Authentication or Windows Authentication)
  
  

  

 Web.Config

• Create a backup of the following file: C:\Program Files (x86)\Quest\ArchiveManager\WebService\web.config.
• Edit the original file and look for the <authentication mode="x">.
• Edit the variable within the quote marks to match the authentication method enabled within IIS manager.
• Restart IIS
