Hi @YutongTie-MSFT ,
Here is the link again: [https://answers.microsoft.com/en-us/msoffice/forum/all/unable-to-access-work-admin-account-due-to/8801f5ce-eafa-4eaf-bd96-ee5535d54bdd That issue was resolved by a tech on the backend if that helps.
I suspect that the Certificates & Secrets permissions issue is related, but that's just a guess.
