Sending, receiving, and organizing email in Outlook.com
For Outlook.com and Outlook on the web, if messages are being flagged as junk even after removing and re-adding the account, the supported checks are:
- In Settings > Mail > Junk email, review these lists:
- Blocked senders and domains
- Safe senders
- If a sender or domain was blocked by mistake, remove it from Blocked senders and domains.
- Add trusted senders or domains to Safe senders.
- If a message is already in Junk Email, open the Junk Email folder, select the message, and choose It’s not junk or Report > Not junk.
- Check the Junk Email folder regularly. Junk email is retained for 30 days before automatic deletion.
- Since rules were already checked, also verify there is no blocked sender entry causing the behavior. For Outlook.com, Microsoft also documents checking whether mail is being sent to Deleted Items by mistake because of a blocked sender or an inbox rule.
If the issue is on Outlook desktop rather than Outlook.com, also check whether Permanently delete suspected junk e-mail instead of moving it to the Junk E-mail folder is enabled:
- In Outlook, go to Home > Junk > Junk E-mail Options.
- On the Options tab, clear Permanently delete suspected junk e-mail instead of moving it to the Junk E-mail folder.
