Log entries show that tool is not able to open the message store. Please refer to Event 9175: The MAPI Call 'OpenMsgStore' Failed with the Following Error and see if it helps.

I can access the mailbox from Outlook, from the link it said

This issue can occur if the information store is not running. When the information store is stopped and the System Attendant is still running, the System Attendant keeps the MAPI session active. This issue can also occur if a mailbox store failed to mount.

But my exchange server still up and running till now, just for migrating to zimbra said that could not access..
