|As previously announced in (MC275573 – Aug), the legacy version of the Service Communications API will be retired on December 17th, 2021. The new service communications API in Microsoft Graph replaces the legacy version of the API and provides access to Message center and Service health posts for your tenant.
When this will happen:
The new API is now broadly available and the legacy version of the Service Communications API will be retired on December 17th 2021.
How this will affect your organization:
Any users, applications or tools using the legacy Service Communications API endpoint via https://manage.office.com will no longer be able to pull service health or message center communications when this change goes into effect on December 17th 2021.
What you need to do to prepare:
Instead of using the legacy Service Communications API, we recommend using the new Service Health and Communications Graph API.
