Description
Don’t move email to my Junk Email folder
Select this option if you want to turn off junk email filtering. If you select this, you won’t be able to use any of the other options on this page.
Warning:Â If you select this option, email detected as spam by Exchange Online Protection will be delivered to your Inbox if the spam action set by your administrator is to move these messages to the Junk Email folder.
Automatically filter junk email
Select this option if you want to use junk email filtering. This filter is in addition to the junk email filter that’s been set by your administrator.
Safe Senders and Recipients
Safe senders and recipients are domains and people whose email you don’t want diverted to your Junk Email folder. Add senders you trust and recipients that you don't want to block to this list. For more details, see Safe senders and recipients.
Trust email from my contacts
If you select this check box, email from any address in your contacts folders will be treated as safe. For more details, see Safe senders and recipients.
Blocked Senders
Blocked senders are domains and people you don't want to receive email messages from. Messages received from any email address or domain in your blocked senders list are sent directly to your Junk Email folder. For more details, see Blocked senders.
Don’t trust email unless it comes from someone in my Safe Senders and Recipients list or local senders
In addition to Safe Senders and Recipients and Blocked Senders, you can use this setting to treat all email as junk unless it comes from someone included in your Safe Senders and Recipients list. For more details, see Blocked senders.
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 sent to your Junk Email folder.
IMPORTANT: The server that hosts your mailbox may have junk email filtering settings that block messages before they reach your mailbox.
