How Safe Is Outlook?

I have recently read an organisation's instructions about the communication of confidential information. It said that if email was used confidential information could only be included if the email was sent from one Outlook account to another Outlook account. That made me wonder if Outlook is somehow safer or more secure than other methods. Is it safer?

 

Unless encrypted email is used via a mail program, where the sender and receiver have the encryption key, no email is actually confidential. Outlook is no different to any other email provider.

If it's Outlook.com you are asking about - Microsoft's online email service - then, as Max says it is no safer than any other email service. But larger organisations don't use that, they mostly use the Outlook component of Microsoft Office and the Microsoft Exchange servers. This has the security features commercial organisations need and is probably what you were reading about.
