I've noticed that cloud policy has stopped working last week. I've raised Microsoft case, unfortunately support is terrible so maybe you will be able to help me. In short: Last week I've noticed that new Office 365 users miss our configuration (cloud policy), then I've tested on my own computer. I've deleted this registry key: Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\CloudPolicy , and nothing happens if I run office software, this key is still missing. I thought maybe this our proxy issue or something similar, but I've same problem on my test tenant where I have full access to the internet and no antivirus. Maybe this is know issue already? We had to stop our migration to Office 365. Environment: windows 10 and 11, Office version: 16.0.15028.20248 Monthly Enterprise Channel.
