Can I perform a mail merge with a datasource that is located on an http location?
A14: No, you cannot perform a mail merge with datasource that is located on an http location, including a SharePoint location. When you try to do this, you may receive an error message. To work around this issue, you need to save the datasource file either locally or onto the network drive (Mapped/UNC path). After you do this, you can perform a mail merge.
