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.

Note: If the instructions don't match what you see, you might be using an older version of Outlook on the web. Try the Instructions for classic Outlook on the web.

If you're receiving unwanted email, you can block the email addresses and domains you don't want to receive messages from. Add any email address or domain to your blocked senders list to move these messages directly to your Junk Email folder.

Note: Email is automatically removed from the Junk Email folder after 14 days and can't be recovered after that. For more information, see Recover deleted email messages in Outlook on the web.
