Sending, receiving, and organizing email in Outlook.com
Hello,
- Could you please confirm whether you have a personal account or a work/Microsoft 365 business account?
- What is the exact error message the sender receives when trying to email your address?
Please send a test email from one of your Microsoft accounts to the affected email address. If you receive a bounce-back delivery error message, please share the complete message here.
Alternatively, see if all of your incoming emails are being forwarded to another email address.
- Go to https://outlook.live.com/ and sign in with your Microsoft account.
- Select the Outlook Settings icon > Mail > Forwarding & IMAP.
- If your incoming emails are being forwarded to another address, click the 'Do not forward' option.
Also, check your email rules, see whether you have enough storage to send or receive emails, and try resetting your Microsoft account password.
