If you're receiving unwanted email, you can block the email addresses and domains you don't want to receive messages from. Add any email address or domain to your blocked senders list to move these messages directly to your Junk Email folder.

Junk email is retained for 30 days before it is automatically deleted and is not recoverable. For more information, see Recover and restore deleted items in Outlook.
