Out of office is a space or block of time when the inhouse personnel will not be available to be assigned to a task. For example, out of office can be implemented to assign leaves of absence, vacations, doctor appointments, etc.
To add an out of office, go to the teams submodule in the profile of the inhouse personnel in question (this user profile should already be associated to a teams schedule).
Then click on the add option to open a new window where you can add the description, type and dates associated with the out of office you want to add.
Lastly, click save to establish the out of office for the person in question.
