Currently only delegated user permissions are supported, and this is very sub-optimal for bots and service applications that need to monitor Teams presence of users.
We have a employee status app for Slack that lists all employees and their current status on a web page using the Slack presence API.
We are moving to Teams since we are already an O365 E5 subscriber.
Management rely heavily on employees using the custom status feature of Slack and would like to see that in Teams. This feature enables employees to give a more detailed status than the canned available, busy, out of office etc,
Also, the ability for one or more designated senior staff to be able set someone's status in their absence would be good. We frequently have employees go on PTO and forget to set their status appropriately. Would be handy for the CFO to be able to override to accurately reflect where someone is or is not
