Suspicious activity account: Microsoft you have lost a paying customer

technically if you have a live sub that is paid monthly then it should not end BUT if the account is inactive, basically not signed into at all on any Microsoft service then they could cease the sub and close the account, technically questions should be asked why they continue to let someone actively pay a sub without actually using the account at all for 5 years without finding that suspicious.

Probably he accessed the account in another country, so this problem, go to Microsoft account and safely say it was you who accessed the account, so the system will not treat it as a suspicious activity

if you cannot access your microsoft account and have 2fa active then they are right all is lost, and as the microsoft account is the account that minecraft migrated too you have now lost minecraft if you cannot access the microsoft account.

Have you gotten any emails about suspicious behavior or activity on the account? Or is it as simple as you forgot your password
