Sending, receiving, and organizing email in Outlook.com
Hi,
I will walk through a few steps with you. Some of these are just to help figure out what is wrong, not to fix it right away. So if nothing changes after a step, that is normal. I will keep going until we solve it.
Was your account hacked sometime back?
Please go to https://outlook.live.com/mail/options/general/timeAndLanguage page. A language change option will appear as indicated in the arrow.
I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!
