Using older Outlook versions with the classic interface and pull-down menus? Then proceed as follows:
Step 1: From the settings, select “Actions” > “Junk E-mail” > “Junk E-mail”.
Step 2: In the “Options” tab, switch the spam filter to “Low” or “High”. Try different options to suit your needs. In the coming days and weeks, check the junk folder regularly. If too many “normal” emails end up there, set the Outlook spam filter to “Low”. If, on the other hand, your mailbox is flooded with annoying spam, set it to “High”.
The option “Safe Lists Only” is, as with newer Outlook versions, rather impractical for most users. You would first have to manually enter all eligible sender email addresses into a list of secure senders.
Step 3: In the “Blocked Senders” list you can see all the senders that have already been blocked. By clicking the “Remove” button you can remove individual email addresses from the blocked senders list.
Step 4: With the “International” tab, domains from selected countries can be marked as spam. For example, if your company specializes in maintenance services for oil heating systems in North Rhine-Westphalia, it is unlikely that you will receive an email request from Vanuatu that is anything but spam.
Step 5: If a junk email is not automatically recognized as such by the Outlook spam filter and ends up in your inbox, right-click on it and select “Junk E-mail” > “Add Sender to Blocked Senders List” from the context menu. Thus, in the future, all emails from this sender will go directly to the spam folder.
Step 6: The spam emails will be placed in the “Junk” folder in the respective email account. You should check regularly to make sure that no unwanted emails have ended up there.
Step 7: If an email is incorrectly marked as spam, right-click on it and select “Junk Email” > “Add Sender to Safe Senders List” from the context menu to prevent emails from that sender from being filtered as spam in the future.
