We will be removing support for the Office Discovery Service from Office 365, beginning November 1, 2019.
We will also be removing the Live Connect API’s and Live SDK, on November 1, 2018
Over the last few years, we have been investing in services that help developers access information in Office 365 in a simple and intuitive way. As we make progress in this journey, some technologies become obsolete, since they no longer provide the best way to interact with Office 365 data. The API’s we are removing, have been superseded by the Microsoft Graph.
How does this affect me?
Beginning November 1, 2018, any code using the Live Connect API’s and Live SDK will no longer execute. Note: Some of the Live Connect API’s will stop working before the API is fully decommissioned. In particular, the profile, contacts and calendar APIs will stop returning user data, on December 1, 2017.

Beginning January 10, 2018, newly registered apps will not be able to access the Office 365 discovery service.

Beginning November 1, 2019, any code using the following sets of API’s will no longer execute:
– Office 365 Discovery service in the endpoint https://api.office.com/discovery

If you are building applications for Office 365, your app using these API’s will cease to function correctly, when this change is implemented.

You are receiving this message because our reporting indicates you are a developer of applications on Office 365 and may be affected by this change.

Around the middle of 2018, we will expand our notification to all Office 365 tenants with applications using these API’s. That notification may result in an increase in requests for app updates from their partner or consultant.

What do I need to do to prepare for this change?
If you have written your own code using these API’s, you will need to update your code to use the new Microsoft Graph, before these changes are implemented.

If you have written code using these API’s, for your Office 365 customers, we recommend you reach out to them with updates by the middle of 2018.
