I am building a web application that needs to fetch all tasks from an organization that uses Outlook Task. Can this be done with Microsoft Graph or Office 365 REST API?
I haven't found any calls in the documentation of either services that would do something similar to that: https://outlook.office.com/api/v2.0/tenant/tasks
Should I find another approach or is it something that is doable?
Outlook Tasks is available in Preview on Microsoft Graph today:
GET /users/{id|userPrincipalName}/outlook/tasks (Graph Explorer example)
I'm afraid I don't have an ETA for when this will be generally available at the moment. According to the Change Log this functionality was added in April so it is still a somewhat recent addition.
This functionality is also available as part of the Office 365 REST API.
If you're looking for something production ready today, you may need to use this API instead. If possible, I would suggest waiting for Graph. Graph is where all future engineering energy will be focused and is the best long-term integration play.
