Task API changes to date properties on beta endpoint

I wanted to update you all on a breaking change that impacts the Task API on the Outlook REST API Beta endpoint. This change is going to be enabled in worldwide production by mid next week.

This is a schema change related to date/time property names and types in the Task entity as follows:

Old name Old type New name New type
CompletedDate Edm.DateTimeOffset CompletedDateTime Microsoft.OutlookServices.DateTimeTimeZone
DueDate Edm.DateTimeOffset DueDateTime Microsoft.OutlookServices.DateTimeTimeZone
StartDate Edm.DateTimeOffset StartDateTime Microsoft.OutlookServices.DateTimeTimeZone
ReminderDateTime Edm.DateTimeOffset ReminderDateTime Microsoft.OutlookServices.DateTimeTimeZone

More extensive documentation on the new functionality is coming soon in our API reference documentation page. Please let us know if you have any questions, and visit https://developer.microsoft.com/en-us/outlook/ for the latest news and updates.
