Hi Frances
I understand you’re having an issue where your Hotmail/Outlook.com mailbox is no longer receiving email from a specific Yahoo sender (it worked until today), while you can still send messages to Yahoo. I’m happy to help.
Please confirm:
- Does this affect only one Yahoo address, or any Yahoo sender?
- Does the Yahoo sender receive a bounce / non-delivery report (NDR) when they email you?
Meanwhile, please also try out these steps:
1) Confirm whether this is sender-specific or mailbox-wide
Send a test email to your Outlook.com mailbox from a non-Yahoo sender. If other senders arrive normally, the problem is likely specific to that Yahoo sender or how their messages are being handled.
2) Make sure the message isn’t landing elsewhere in the mailbox
If Focused Inbox is enabled, check both tabs:
Also:
- Check Archive and Deleted Items
- Use Search for the Yahoo sender name/address or a subject keyword
3) Check “Sweep” actions and forwarding settings
Outlook.com includes Sweep, which can automatically move or delete messages from a specific sender. Also verify Forwarding is not enabled (forwarding can redirect mail away from your inbox): Settings > Mail > Forwarding.
4) Check mailbox storage and known Outlook.com storage behaviors
If your mailbox/storage is full, messages may fail to deliver and can bounce back to the sender. Also, review current known issues/workarounds here: Fixes or workarounds for recent issues on Outlook.com - Microsoft Support
5) If only that Yahoo sender is affected, ask the sender to check their side
Please tell me how it goes. If the problem persists, please don’t hesitate to reply to this thread and I will be happy to help. Have a lovely day!
