Try Get-MailboxDatabase. Do you get the same error message? Did try restarting the server? Also, trying restarting the Microsoft Exchange Replication service.Santhosh Sivarajan | MCTS, MCSE (W2K3/W2K/NT4), MCSA (W2K3/W2K/MSG), CCNA, Network+ Houston, TX http://blogs.sivarajan.com/ http://publications.sivarajan.com/ This posting is provided "AS IS" with no warranties, and confers no rights.

Hi, About event ID: 4098,please see this thread. And post the results here. http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/74418ffb-4819-4693-9b58-78dfbb8e0b65 But I think these two events are not related with your question: "I cannot access exchange through Exchange Management Console". Could you please post the error message here? Or will this link be helpful?
