This SharePoint library or list data connection was created using an older format. Convert it to the Infopath 2010 or greater format before saving the form template

SharePoint / Azure / Office 365

This usually happens after you migrate an InfoPath form to a grater version and you change the Compatibility Mode (File – Form Options – Compatibility – Form Type…)


– Open the InfoPath form in design mode

– Click on Data – Data Connections

– Select a connection and click on Convert to Current Version if that option is visible
