Hello, We have rebooted all of our servers. The exchange 07 server, seems to be up and running fine, but we can't get the outlook to work. When we try to do a send and receive in outlook I get this message:Task 'Microsoft Exchange Server' reported error (0x80040111) : 'The server is not available. Contact your administrator if this condition persists.' When I try to access email via web I get the error below after I enter the user name and password.

Ok so far we see its an issue on your Mailbox server, lets check a couple of things before geting into depth. Give the following commands and tell me: Test-MapiConnectivity - THis cmd will try to log on to the System Mailbox, lets see if it gives us any error. Test-ServiceHealth - This will point you if any required services are stopped. "The Test-MapiConnectivity cmdlet verifies server functionality. This cmdlet logs on to the mailbox that you specify (or to the SystemMailbox if you don't specify the Identity parameter) and retrieves a list of items in the Inbox. Logging on to the mailbox tests two critical protocols used when a client connects to a Mailbox server: MAPI and LDAP. During authentication, the Test-MapiConnectivity cmdlet indirectly verifies that the MAPI server, Exchange store, and Directory Service Access (DSAccess) are working." Which application log event errors are appearing on your mailbox server?

Hello, Judging by the error message I would say that the problem should be pretty obvious, in the lines of databases not being mounted or services that are not started. I would suggest to make a quick assesment , check the state of all the exchnage related services, and check the status of the databases in the Exchnage System Manager. Hope it helps,

Hope it helps, Yes I would also suggest to check Mailbox Database and Information Store or Service Host services on MBX server. I guess your MBX DB is not mounted after reboot. This can occur in scenarios where you have more MBX DBs to be mounted at a time than allowed by the Exchange Edition ( 5 in case of Exchange Standard edition).

Hi, How about your question now ? Any updates? Please also run the ExBPA in the toolbox. Is there any error event logs in the Event Viewer?Frank Wang
