Outlook blocking attachments
If you have Outlook 2003 save the file Lvl1Remove.reg.txt to your computer. Remove the “.txt” from it and then double click on it. Allow it to merge with your registry.
Use Lvl1RemoveXP.reg.txt in the same manor, by renaming it to Lvl1RemoveXP.reg, then double clicking on it and allowing it to merge with your registry.
Nothing terribly bad will happen if you use the wrong version, it will just save to a registry key your version of Outlook isn’t looking at.
