If you want to discover if a colleague is in the office or if you want to find where they are sitting, you can search for them in the Office Schedule.
To do so, go to Officely Home -> View More (on the day in question) -> enter their name in the search bar. Officely will then show the Neighbourhood they are sitting in (if they are booked into the office).
