Remove Team Calendars from Outlook's Navigation Pane

A user wanted to know if it was possible to disable the Team calendars that are listed on Outlook’s calendar navigation pane. While it can be handy for users who manage one or a small number of calendars, the navigation pane is cluttered when the user manages several calendars.

Sure. Individual users can expand the Calendar Groups button in the Manage Calendars chunk and deselect Show Team Calendars.

This can also be controlled through group policy. In the policy editor, browse to Outlook, Outlook Options, Preferences, Calendar Options, Schedule View.
