To Do sync with Microsoft ToDo

Please make it possible, to sync the new ToDo with Microsoft ToDo, planner/project.

Agreed. This would be a great addition. Right now, I have HA connected to Todoist, which connects to Amazon Alexa and MS Todo.

I can add items via Amazon Alexa, and they show up in Todoist and they show up in HA and they are being added to MS Todo. But if I eliminate an item from HA, it unfortunately remains in MS Todo.

There is also this microsoft todo api To Do API overview - Microsoft Graph | Microsoft Learn

There’s this very cool solution: GitHub - RogerSelwyn/O365-HomeAssistant: Office 365 integration for Home Assistant

This supports the To Do functionality in HA and can show Microsoft To Do tasks in there.
