Is it a network effect if it's only within a company? For example, because there isn't any (good) data model that allows for resource reservations, calendar systems within a company are always on the same platform so there aren't conflicts in booking meeting rooms (which, even when calendar programs were on the same platform, was a big problem from around 1995-2000). But that doesn't mean people outside the company can't use a different calendar program and send .ics invitations.
