“The Server Is Unavailable” for a Single Exchange 2010 User

I have one single user who cannot open Outlook 2010 connected to Exchange 2010.  The server is up and everyone else with Outlook connected to this same server is up and running.  This one user gets the following dialogue in front of the Outlook 2010 splash screen: Connecting "The server is unavailable." Retry | Work Offline | Cancel

If selecting Work Offline, a new dialogue is displayed: Microsoft Outlook "Cannot Start Microsoft Outlook. Cannot open the Outlook window.  The set of folders cannot be opened. The information store could not be opened." OK is the only option here.

If I try to open Control Panel | Mail (32bit) I get the same as the first dialogue: Connecting "The server is unavailable." Retry | Work Offline | Cancel but this time, Work Offline does allow getting in to see their Exchange connection.

I deleted the email account in control panel and upon trying to re-add it (we are using autodiscover) I get the dialogue: Microsoft Outlook "The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action." OK is the only option here.

It takes me to what should be the next screen with Microsoft Exchange server name resolved but Mailbox unresolved.  I click OK and get: Microsoft Outlook "The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action. OK is the only option here.

Before removing the account from Control Panel | Mail (32bit) I tried
Set-CASMailbox -Identity <UserID> -MAPIEnabled $false
Set-CASMailbox -Identity <UserID> -MAPIEnabled $true
in Exchange Management Shell to close all of the users connections but that did not help.

I am attaching screen shots of all of the dialogue boxes I mentioned.

Can the user open their E-Mail in OWA?

Have you tried logging in as yourself on the machine and then seeing if you can create yourself a mail profile in Outlook? Atleast then that will help narrow down where the issue is.

Yes, the user could login to OWA no problem.  We then found we could NOT add a profile / email account for them to Outlook on another PC.  A few days ago the server harddrive was nearly full, I had an Exchange specialist remote in and delete "some stuff."  I can't be more specific, I was trying to catch a plane so I didn't ask a lot of questions, I trust this person.  They said they checked the database and all looked good but maybe they should have rebooted.  I rebooted the server, added a new profile and account on the PC of the problem user and now it works great.  I also had a couple of people still unable to connect to Exchange.  For these I deleted and recreated their profiles on their PC and all is well.
