Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Jarosław,
This is a widely reported scam on Discord joining a server, you get redirected to a fake page to enter your details and that gave them full access to your account and they immediately change the recovery details like the associated Email to block you from accessing the account.
This forum is just a user to user account and no-one here has any account access or the ability to recover a hacked account, I wish I had better news, but when a Microsoft account is hacked, if the hackers change the associated Email or if 2FA is enabled on the account, then that account is usually no longer recoverable, try using the process they provide on this link to recover a hacked account, if this process is not successful, sadly, that account cannot be recovered.
