Block senders or unblock senders in Outlook on the web

You can block messages from specific email addresses or domains from reaching your inbox. When you add an email address or domain to your blocked senders list, Outlook on the webautomatically moves messages from that sender to the Junk Email folder.

Note: You can have up to 1,024 addresses or domains in the blocked senders and safe senders lists. If you want to add more than that, try blocking domains instead of individual email addresses.
