Hi, you can try use eseutil with some parameters on the database - ....\Microsoft\Exchange Server\Bin\esutil.exe (/p; /d; ..) JD

What events are logged in event log ? You can check this article. It could help. http://support.microsoft.com/kb/925825

I saw this on my VM environment. Might not the best solution, but restarting the server solve the problem =)
