As announced in April 2023, Microsoft has been implementing a global umbrella domain (cloud.microsoft) for Office 365 services (Office 365 – New unified domain for Office 365 services (hametbenoit.info)).
After moving some services (Office 365 – Transitioning to cloud.microsoft domain (hametbenoit.info) and Office 365 – Continuous move to cloud.microsoft domain; new services moved (hametbenoit.info)), new ones are getting moved under the cloud.microsoft domain:
- Microsoft 365 Copilot Business Chat https://m365.cloud.microsoft/chat
- Microsoft OneNote https://onenote.cloud.microsoft/
As always with such move, the current URL will still be available for a bit of time and then a redirection will be set in place.
