XWEB: Information Store Logs 1219 Events When Browsing Public Folders

When you browse public folders anonymously using Outlook Web Access (OWA), you may see 1219 events logged by the information store in Event Viewer on the Exchange Server computer. The event contains information similar to the following:

The event ID 1219 is logged because OWA uses the Anonymous account permission assigned to a public folder. You can view this using the HTTP Protocol Properties dialog box in the Microsoft Exchange Server Administrator program. Click the HTTP (Web) Site Settings object in the Protocols container under the Configuration container, and click the Folder Shortcuts tab. Display the properties of the selected public folder, and click Client Permissions.

Although the 1219 event is logged, the functionality of browsing public folders anonymously is not affected. The event is merely a symptom of the information store being unable to authenticate the logon because the Anonymous account is being used.
