(HttpResponseMessage response = await client.SendAsync(request))

i.e

You have to register your application on Azure Active Directory (AAD) and set the application permissions to read emails in your app registration.

Check out this presentations starting fromr slide #24: http://www.mostafaelzoghbi.com/2015/10/identity-and-office-365-presentation-on.html

Hope this helps.

Exchange mailbox access by API was disabled for that account. Please follow https://msdn.microsoft.com/en-us/library/office/dn467892(v=exchg.150).aspx to enable it, e.g. Set-CASMailbox –Identity [email protected] -EwsEnabled:$true
