개인 Outlook.com 계정 설정, 보안 및 개인 정보 관리
Hi Yejin,
Sorry you're having issues with the automatic translation. I have disabled.
I would not worry about the previous mailbox. Once deactivated, the mailbox will be mark for deletion after so many days.
If you still receive the error message, I would suggest creating a new profile. I prefer to do this from Control Panel / Mail / Show Profiles / Add.
Thanks,
Brian
