To stop PayPal messages going to Junk in Outlook on the web (Microsoft 365), configure both Safe Senders and Blocked Senders, then use the built‑in “Not junk” action so Outlook learns correctly.
- Add PayPal to Safe senders and domains
- In Outlook on the web, select Settings (gear icon) at the top.
- Select Mail > Junk email.
- Under Safe senders and domains, select Add safe sender.
- Add the PayPal address or domain (for example, the exact From address shown on a PayPal email, or the domain part only).
- Select OK, then Save. Messages from addresses or domains on the safe senders list will not be moved to Junk.
- Check Blocked senders and domains
- Still under Mail > Junk email, look at Blocked senders and domains.
- If any PayPal address or domain (or a broad domain that might include PayPal) is listed, select it and remove it.
- Select Save.
- Mark existing PayPal messages as not junk
- Open the Junk Email folder.
- For a PayPal message, use the Not junk / Not spam option (or drag it back to Inbox). This helps train the Junk Email Filter that these messages are legitimate.
- Review Junk Email settings in classic Outlook (if also used)
If classic Outlook for Windows is also in use, ensure the Junk Email Filter and safelist collection there are not blocking PayPal:
- In classic Outlook, select Home > Block > Junk Email Options.
- Confirm PayPal is not on Blocked Senders and optionally add it to Safe Senders.
After these steps, new PayPal messages should stay in the Inbox instead of going to Junk.
