Outlook 2003 client cannot connect to Exchange 2010 mailbox after client power fail.

An outlook client was connected to Exchange 2010 when the power cord to the client machine was pulled. Now the client gets an error "Unable to open your default e-mail folders. The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance. (/0=......). Neither of the above conditions exist. The client can ping the Exchange server and can access all network resources. I deleted and recreated the user's mail profile. I also cannot connect to the mailbox from any other machine via outlook. I am able to create a mail profile for another active mailbox on this client machine and it connects ok.  I am able to access the errant mailbox via OWA. It appears that the mailbox on the Exchange server has somehow disabled MAPI access. I checked the mailbox properties and disabled and then re enabled the MAPI protocol, still not good. Cache mode is disabled on the client.

Try performing a mailbox repair to see if it'll fix the issue: http://technet.microsoft.com/en-us/library/ff625221%28v=exchg.141%29.aspx

Yes, as I stated above it is accessible via OWA.

My plan was to reboot the Exchange server after hours last night. However, before I did that I tested it again and it was working. So I am not sure what the problem was but it is fixed for now.

Thank You Larry and VB ITS for you response.
