Users stay 'available' when computer logged off/turned off

If you could please ask the user who is experiencing the incorrect presence go to the bottom left of their client where the little question mark is and submit feedback, that will notify the Teams team of the issue.  We are looking at some presence inconsistencies right now and this data will help us identify what might be causing it.  Like Juan Carlos said, it might be due to some of the things the service is doing to focus resources on other areas of the product but it'd be great to get the information from that users machine.  Thank you so much for reporting!
