The first thing to do is to establish whether or not the problem is generating an error message. Almost all problems in Windows and Microsoft applications have an error message or number.
For instance, your error might be due to your email account being incorrectly configured. You should read our guide on setting up an email account in Outlook before proceeding.
Alternatively, you might be getting the message “Cannot connect to server”. This can be a frustrating fault, and tracing it can be difficult.
Finally, you should consider what sort of email account you have. For instance, is your email account associated with your job? Are you attempting to access email from home, or somewhere within your organisation?
Problems connecting to Outlook from within an organizational extranet may well be due to downtime on the email server, but can be diagnosed using our article Cannot Connect to Server.
