Outlook - Exchange Connection Error

I have a single user having this issue, all other users are working properly.

Problem started when we migrated from Exchange 2007 to Exchange 2013

When opening Outlook 2013 to connect to On-Prem Exchange 2013 server, getting the following error:
Microsoft Outlook
Cannot Start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the exchange server is down for maintenance.

Troubleshooting already attempted
  • Removed Users Exchange account, and recreated = Problem still happening
  • Moved Users mailbox to different Exchange Database
  • Problem occurs on different system (follows user)
  • Only occurs with the single users, all other users work properly
  • Outlook Web Access works properly for the user.

Problem occurs on different system (follows user)

Does the user have a roaming profile?

Not a Roaming Profile

I was going to suggest this
Try to reset the navigation pane and check if it helps.

    Ensure Outlook is closed,
    Hold Windows key + R.
    Copy and paste, or type the following command in the Open box, and then press Enter:

Outlook.exe /resetnavpane

Note: There is a space between Outlook.exe and /resetnavpane.

If it were a roaming profile. you might try it just for grinns. you never know.

The example shows adding a new profile but you can also delete it and and new.

Is it a physical machine or virtual? Do you have any profile management. If OWA is working and it is the specific user have you tried to repair or reinstall Office 2013 on that specific machine?
