Junk Email Filter Lists
Safe Senders list tab | Email addresses and domain names in the Safe Senders List are never treated as junk email, regardless of the content of the message. You can add your Contacts and other correspondents to this list. However, by design, safe domains are not recognized by default in Exchange Online or in Exchange Online Protection. Only blocked domains, blocked sender addresses, and safe sender addresses are recognized. If you use a Microsoft Exchange account, all names and addresses in the global address list (GAL) are automatically considered safe.
Safe Recipients list tab | If you belong to a mailing list or a distribution list, you can add the list sender to the Safe Recipients List. Messages sent to these email addresses or domain names are never treated as junk, regardless of the content of the message.
Blocked Senders list tab | You can easily block messages from particular senders by adding their email addresses or domain names to the Blocked Senders List. When you add a name or email address to this list, Outlook moves any incoming message from that source to the Junk Email folder. Messages from people or domain names that appear in this list are always classified as junk, regardless of the content of the message.
International tab, Blocked Top-Level Domains list | To block unwanted email messages from another country/region, you can add country/region codes to the Blocked Top-Level Domains List. For example, checking the CA [Canada], US [United States], and MX [Mexico] boxes in the list blocks messages from email addresses that end in .ca, .us, and .mx.
International tab, Blocked Encodings list | To block unwanted email messages that appear in another character set or alphabet, you can add encodings to the Blocked Encodings List.

No matter how Andrews faculty and staff access their email, whether through Outlook (the recommended app), Outlook Web App or through a mobile device, the protection will be in place. Offic 365 users will not notice any aesthetic change to either Outlook or OWA, they may notice a decrease in spam.
