Symptoms

I recently uninstalled a previous version of Microsoft Office and installed the latest version of Microsoft Office as part of my Office 365 Premium subscription.  However, I receive the following error message when I try to launch Microsoft Outlook:

“Outlook cannot log on.  Verify you are connected to the network and are using the proper server and mailbox name.  The Microsoft Exchange information service in your profile is missing required information.  Modify your profile to ensure that you are using the correct Microsoft Exchange information service.”

Cause

Parts of your email profile from a previous version of Microsoft Outlook were left behind and prevents the newer version to launch properly.

Solution

Delete all registry keys under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles\Outlook
