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).
Organizations using these products are advised to update their systems and documentation to ensure continued access. Microsoft has told customers to review configurations on client devices, proxies, firewalls, secure web gateways, or other enterprise network controls to confirm that users can connect to the new addresses. Companies having trouble connecting should ensure that their environment aligns with the recommended network requirements for Microsoft 365 Copilot.
