Overview of the Junk Email Filter

Use Junk Email Filters to control which messages you see

Prevent false positive email marked as spam with a safelist or other techniques

Spam and junk mail are unavoidable parts of having an e-mail account.

Here's how you can deal with junk mail in Outlook.

Select the e-mail that you want to mark as Junk, and you can either right-click on the e-mail, select Junk, Block Sender, or from the Home ribbon tab you can also select Junk, and then Block Sender.

The sender of the message will be added to the blocked senders list and the message will be moved into the junk e-mail folder.

Depending on who your e-mail provider is, the folder may be called something different depending on who your e-mail provider is.

It's commonly called Junk, Junk Mail, or Spam.

In this case I have a Gmail account, so the folder is called Spam.

Let's go in this folder just to make sure there's nothing else in there that's really not spam.

Here's something in here that's very clearly not spam.

I'll right-click the e-mail, select Junk, and then I'll select Not Junk.

The message will be moved back into the Inbox folder, and I can choose to always trust e-mail from this person.

This way it will never get marked as junk again.

I'll click OK, and now I can go back into my Inbox and see the message that we marked as junk previously.

At any time, you can go into your junk e-mail settings, and either add people to your block list, or remove them from your block list.

Select Junk, and then choose Junk Email Options.

The first thing you can decide is the level of automatic junk e-mail protection you'll start with.

Outlook defaults to not filtering any junk mail for you, meaning you have to right-click the message and select Junk Mail itself.

However, you can go through these options and choose the one that you're the most comfortable with.

I like Low, meaning it automatically flags things that are very obviously junk messages.

From here, I can change to the Safe Senders tab.

This is a white list of e-mail addresses that Outlook will always accept incoming mail from.

I can manually Add somebody to this list at any time by clicking Add, and I can Remove somebody by selecting their name and clicking Remove.

Just like there's a Safe Senders list, there is also a Blocked Senders list.

This is a list of people that it will always block messages for. If you have the same e-mail address on both lists, Outlook will use the Safe Senders list first.

I'll highlight this name from the Blocked Senders list, and choose Remove.

I'll click OK, and now I'm brought back to my inbox.
