Hello, thank you for reaching out to Microsoft Q&A.
Microsoft has implemented several AI filters to block junk/spam emails delivered to your inbox; however, some emails slip through the cracks.
- Are these emails from a specific sender, and do they have the same subject line?
- Are you receiving emails from different senders, even after adding those senders to your blocked senders list?
If the emails are being delivered to your Junk Email folder, it means Microsoft’s junk email filter is working correctly by categorizing them as junk. Emails in this folder will be automatically deleted after 10 days.
However, if the emails are being delivered directly to your Inbox and are not being filtered,
- Create a new email rule using a specific sender address or subject line, then move those emails to the Junk Email or Deleted Items folder. Then,
- Add the sender’s address to your Blocked Senders list.
To create a new email rule, sign in with your account here -
https://outlook.live.com/mail/0/options/mail/rules
Click "New Rule". Then add a condition and action.

To add the sender's address to the blocked sender list,
Go to Outlook Settings > Mail > Junk email > Blocked Senders and domains.
Add the spammer's address there.
In addition to this, ensure you have secured your account with a
- Strong Microsoft account password and
- Having enabled two-factor authentication for added Security.
