Teams and Copilot are changing addresses: update your firewalls

Microsoft is changing the destination address of two of its most popular services: starting this month, it will redirect M365 and Teams web users to copilot.cloud.microsoft and teams.cloud.microsoft, respectively. The Teams move is already under way, and Microsoft has now added M365 to the mix. The company announced the changes in two MessageCenter posts: MC1465764 ( mirror ) and MC1462915 ( mirror ).
