Configuring and Using Outlook People Favorites

Outlook people favorites give Exchange Online users fast access to their most important email correspondents. OWA has the best implementation but the feature is also available in Outlook mobile. As usual, Outlook desktop lags. It’s a small feature that could turn out to be very important to some users. Office 365 is full of such examples.
