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.
