Features
Read full description

With this app, Microsoft Exchange Server users can view Public Folder contacts and calendars. Contacts and appointments can be created, edited and deleted. Public Folder Email messages are also accessible but presently view only. This app does not support GMail/GSuite, Yahoo or any other personal email services. This is an enterprise application built for Microsoft Exchange Server. The app does not route your Exchange traffic through a third-party server. The app communicates directly with Exchange Web Services using SSL and it works with On-premise Exchange or hosted Exchange, but not Office 365. For Office 365 Public Folder access, we suggest the CiraSync app. There are no ads and no in-app purchases. We author and support this free application in exchange for receiving quarterly communication from our team. If you have trouble logging in, you can make tech support requests directly through from the app. Otherwise, please visit our website. If you would like to sync the GAL (Exchange Global Address List) to iPhone, please visit our website to learn about our enterprise server software.
