OX Tasks is OX App Suite’s “to-do” list. It lets users handle day-to-day and long-term tasks, and makes sure they get done. Creating new tasks and updating existing ones are as easy as can be. A task form with just two fields lets users create simple “to-do” items. When more details are needed, more functions are available so that even more complex, long-term projects can be managed easily.

For example, it presents latest emails, upcoming birthdays, and open “to-do” items. In addition, users can subscribe to individual news feeds and providers can also customize the portal to place relevant content for their users.




OX mobile apps let users manage their emails, access and share their uploaded documents and pictures, and synchronize their calendars, contacts and tasks with native apps for iOS and Android, as well as clients for Windows PCs and Macs.
