For Admins: How do I disable push notifications for my organization?
Customers using list sharing in Microsoft To Do will soon be receiving push notifications for activity in the lists they share with others. While we've added this feature to make collaboration easier and more valuable, some customers might prefer to disable the feature for their organization.
Once push notifications are released for work and school accounts, admins will be able to turn them off on a tenant-wide level by going into the M365 Admin Center's settings. They will be found under "Microsoft To Do" and there will be a toggle for "Enable Push Notifications" like the one pictured below.
