Microsoft app, part 2

This service will keep on getting users' emails unless it is blocked. It won't stop by removing the app, even if the email accounts is deleted from the app, since the fetching process is handled by cloud service.  Here it goes:  "We provide a service that indexes and accelerates delivery of your email to your device. That means that our service retrieves your incoming and outgoing email messages and securely pushes them to the app on your device.Similarly, the service retrieves the calendar data and address book contacts associated with your email account and securely pushes those to the app on your device. Those messages, calendar events, and contacts, along with their associated metadata, may be temporarily stored and indexed securely both in our servers and locally on the app on your device. If your emails have attachments and you request to open them in our app, the service retrieves them from the mail server, securely stores them temporarily on our servers, and delivers them to the app.”
