Our e-mail system already has a SPAM filtering built into it, so using client based filtering can sometimes become more of a hassle and you might miss some important e-mail messages. You can disable “Junk Mail” filtering in Outlook 2010 by performing the following:
- Open Outlook
- On the Home Tab, Delete Section, Click on the Junk Drop Down
- Select Junk Email Options.
- Click the Options Tab.
- Click No Automatic Filtering.
- Close Outlook and Re-open.
This should disable the Junk Mail filter.
