Sending, receiving, and organizing email in Outlook.com
Hi Christine B
If senders are not receiving any bounce/NDR messages, check your Junk Email, Deleted Items, and Archive folders, and use Outlook.com's search to look for a recently sent message. Also verify that your account's Rules, Forwarding, and any block/safe sender lists have not been changed unexpectedly after the suspicious activity.
If possible, let us know:
- Can you send email successfully?
- Can you receive email from a different email account you control (Gmail, Yahoo, etc.)?
- Do senders receive any delivery failure message?
Feel free to update here if anything comes up!
