Re-establishing Contact with Your Inbox
                     Re-establishing Contact with Your 
Inbox: Outlook Disconnected Solutions. 
 
Outlook Disconnected can be annoying and interfere with your job. To get you 
back online, there are various options available. Make sure your server settings 
are configured correctly and that your internet connection is reliable first. 
Moreover, you may try restarting Outlook, fixing your Outlook profile, or turning 
off any add-ins that might be to blame for the disconnect. Try creating a fresh 
Outlook profile or clearing your network settings if none of these fixes work.
