Entourage 2008 Calendar is empty

CURRENT CONFIGURATION: MacBook Air, Mac OS 10.5.8, Microsoft Entourage 2008 for Mac 12.2.0 (90605) with update 12.2.1, Microsoft Exchange 2007

OBJECTIVE: Use Entourage for Exchange Calendar

ISSUE: Entourage Calendar is empty, but events are exist and viewable on Exchange OWA page.

SOLUTION:
Open Entourage 2008. Enable Folder List. Open Calendar (under your Exchange account name). Create new test event. Expand Calendars Views --> All Events. Find and select the test event. Menu Event --> Move to --> Choose Calendar --> Select Calendar under your Exchange account name.
Select calendar under your Exchange account name in Folder List and check all events.

Is it miracle? I think it is software bug.
