Since the release of Exchange Server 2007, there have been rumors that Exchange public folders are not going to last long in Exchange. Although they are a huge enhancement as far as data sharing and online collaboration are concerned, since the first release of SharePoint Microsoft tried to convince companies to rather use their separate online collaboration platform for data sharing instead. However, over the past releases of Exchange public folders remained and have been even improved. In Exchange 2013/2016/2019 they are not the same public folders anymore. The newest version of Microsoft’s email server introduced a completely new approach to public folders architecture.
