Options > Junk Email

Junk email can strain networks, clog email servers, and fill mailboxes with unwanted messages and images. The server that hosts your mailbox will filter out most junk email, but not always all of it. The light version of Outlook Web App helps you control unwanted and unsolicited messages by letting you manage and create lists of trusted and untrusted email addresses and domains.

To get to the Junk Email page from the main Outlook Web App page, go to the upper corner and choose Options, then choose Junk Email from the list in the navigation pane.

The junk email filter gives precedence to email addresses over domains when it checks incoming messages. For example, suppose the contoso.com domain is on your Blocked Senders List and the address someone@contoso.com is on your Safe Senders List. The address someone@contoso.com will be allowed into your Inbox, but all other email addresses that have the domain contoso.com will be sent to your Junk Email folder.

Note:  When you enter domains in your Safe Senders List or Blocked Senders List, you don't have to include the "at" (@) symbol. It will be added automatically.

Changes you make to the Safe Senders List, Blocked Senders List, and Safe Recipients List are automatically saved when they're entered. If you change any other Junk Email settings, you need to click Save to save your new settings. If you don't click Save before you leave the Junk Email page in Options, you'll be prompted to either click Cancel to remain on the page or click OK to leave the page without saving your changes.

What else should I know?

Sometimes email that you send ends up in someone else’s junk email folder. They will need to make changes in their email program to allow messages from you to be received.
