Cannot connect to Exchange Server After Creating a New Windows Profile

I re-created a client's profile and copied desktop and favorites since her profile was corrupted. However, I could not set up the Outlook to connect to the Exchange server. I had to re-store the user name and password for the windows logon credential and exchange servers and proxy settings since the information was gone when re-created her new profile. We use the exchange server hosted by the third party. There was a new Outlook data file created, but I got a message saying that the connection to Microsoft Exchange is unavailable Outlook must be online or connected to complete this action, then I got a dialog box to verilfy her account and got a message saying that the name cannot resolved, cannot open default email folders, the information stored could not be opened, Finally I go a message saying that cannot open your default email folder, the file C:\the users profile\Application Data\Microsoft\Outllok\Microsoft ost is not a Outlook data file (.ost). But, there was the Outllok Data file with the mark of sync.
This is another issue caused by recreating a new profile.
