Sending, receiving, and organizing email in Outlook.com
Hello, thank you for reaching out to Microsoft Q&A.
Check your email rules to see whether you’ve created one that automatically moves all incoming emails to the Deleted Items folder.
- Go to https://outlook.live.com/ in a private browsing window and sign in with your Microsoft account.
- Select Outlook Settings > Mail > Rules.
- Delete all the email rules you created.
Then go to Settings > Mail > Blocked senders and domains.
If the sender address you want to receive emails from appears in either list, remove it.
This could also happen if there has been suspicious activity on your Microsoft account. So, change your Microsoft account password, then go to the security settings page here and sign out of all sessions:
