If email is going to your Outlook.com Junk folder by mistake, you can mark it as Not junk or add the sender to your Safe Senders list. Marking email as Not junk also helps us improve our service.
To mark an email message as Not junk in Outlook.com
Open your Junk Email folder and select the messages you want to keep.
From the top toolbar, select Not junk > Not junk (or Not spam > Not spam). You can also open the message and select the It's not junk link at the top.
If you've blocked someone by mistake, open your Blocked senders list and select the next to their name.
Add the sender to your Safe senders list.
