Safe senders and recipients
Safe senders are people and domains you always want to receive email messages from. Safe recipients are recipients that you don't want to block, usually groups that you’re a member of. Messages received from any email address or domain in your safe senders and recipients list are never quarantined.
How do I add a sender or a domain?
1. Sign in to Outlook on the web. (Click here to sign into webmail)
2. At the top of the screen, select Settings > Mail.
3. Under Accounts, select Block or allow.
4. To add an entry to Safe senders and recipients, enter the email address or domain that you want to mark as safe in the Enter a sender or domain here text box, and then press Enter or select the Add icon next to the text box.

For example, to mark all email from addresses that end in contoso.com as safe, enter contoso.com in the text box.
