For many years, Microsoft Outlook, part of the Office 365 productivity suite, has had a rudimentary task list that was less than satisfactory and often ignored by users. However, with the widespread release of To-Do for Office 365 subscribers, Microsoft hopes to change our perception of the task list and reignite the to-do-list system as a viable organizational tool for enterprise employees.
I am very surprised how popular the Microsoft To-Do App has gotten. Microsoft has not been over successful with apps besides the Office suite.
