We’re happy to announce the general availability (GA) of the permanent delete APIs for contacts, messages, and events as well as for contact folders, mail folders, and calendars.

This set of APIs is one of several we’re releasing in the coming months to fill gaps in the Microsoft Graph API to facilitate the transition away from Exchange Web Services (EWS).

The following APIs are now GA and available in the v1.0 endpoint:

• Permanent delete for mail message and mail folder
• Permanent delete for event and calendar
• Permanent delete for contact and contact folder

We’re filling gaps in the Microsoft Graph API at an accelerated pace ahead of the retirement of EWS In October 2026. We’ve already unblocked many scenarios and are working hard to achieve parity.

In the meantime, we recommend that you start your migration in advance of the October date to ensure sufficient time to address any issues with the Microsoft Graph APIs before EWS is officially retired.

We’d love to hear your feedback! If you have any suggestions, questions, or issues to report, please leave a comment on this post. Stay tuned for more API updates in the coming months.
