Enify Sign In I Refresh sign in

To secure your account Microsoft has a time-out function. Periodically you will be signed out and you have to sign in again. It is a simple & automatic process.

All you have to do is to click the sign in button when it occasionally appears. If you have previously checked the box "remember my account" it will automatically sign you in again. If not you will have to re-establish your credentials; so consider clicking "remember my account" to make it easier next time.  Have a look at the video below:
