Sending, receiving, and organizing email in Outlook.com
Greetings!
This is Tin, I'll do my best to help. Sorry to hear that the emails in your Inbox folder are missing. May I know if its only the Inbox folder or all of the folders? How do you access your email, via app or browser?
Please try to access it via browser: go to https://outlook.live.com and sign in your account. Please check if you are getting any error or if you will be able to see your emails there. If yes, it means you just need to sign in back your account to the app that you are using.
Please let me know how it goes.
Thanks,
Tin
