Why can't I use my Microsoft address with Clockwise?

At this time, Clockwise is a tool that can only be used with Microsoft 365 Business accounts, because we require access to team calendars to resolve conflicts between teammates.

If you believe you are receiving an error mistakenly, please ensure you are logged in to Microsoft with your Microsoft 365 Business address before attempting to log in to Clockwise.

Clockwise does not support Microsoft Business On-Premises at this time, only Microsoft's cloud-based Business accounts.
