Many people still use Outlook for their emails and get many junk emails coming through but have not taken the time to adjust their junk email settings.
When I visit clients they have never altered their junk email settings as it is usually at the default setting of No Automatic Filtering.
There are however other settings that you can choose which will be far better at capturing Junk
- Low If you don’t receive many junk messages, or want to filter only the messages that are the most obvious junk, select this option.
- High If you receive lots of junk messages, but don’t want to restrict messages from senders on your safe lists, select this option. We recommend you occasionally check the Junk E-mail folder to make sure that a message you wanted isn’t moved in error.
- Safe Lists Only This is the most restrictive option. Any message that isn’t from someone on your Safe Senders List or isn’t to a mailing list on your Safe Recipients List, is classified as junk.
