Outlook.com considers emails from your contacts to be important, so you can simply add an email address to your contacts and emails from that sender shouldn’t be marked as spam in the future.
To do this, click an email from that sender and locate the sender’s email address at the top of the email. Click it and then click the “Add” button. Enter whatever information you want for the contact and then click “Save” to add the email address to your contacts.
While Outlook.com will prioritize emails from your contacts, it may still send them to spam if they look unusually spammy. If emails continue getting sent to your spam even after you add the email address to your contacts, you can completely override the spam filter with the “Safe Senders” list.
To do so, click the gear menu at the top right corner of the Outlook.com website and then click “Options”. Click the “Safe Senders” option under Junk Email and add the sender’s email address to the list here.
