Hello, my client's account can no longer connect to office, outlook, team on his pc, on browser or mobile, it works. I followed the tutorials found via the error code, such as checking the time, the email in the pc settings. I also uninstalled office reboot and reinstalled office but still the same error.
Error CAA20003 and 135011

For this issue, it is not related to windows 365. Windows 365 is a cloud-based service that automatically creates a new type of Windows virtual machine (Cloud PCs) for your end users. To get more help, I will add "Office" tag. Thanks.
