ipm.document to ipm.note converter?

Jul 22 at 8:03 PM
I'm trying to import tons of emails stored on Sharepoint on prem 2007 to our Veritas ev.vault cloud so we can turn off those servers. We've moved to SPO and O365. I opened the sharepoint list in Outlook 2013. Let everything download including headers. Exported to PST. That gives me a PST file with IPM.Document.Outlook.File.msg.15 Veritas is telling me that the messages in the PST need to be IPM.Note not IPM.document. Can MFCMAPI convert them for me? Or does anyone know of how I can convert them? Or should I have done this a different way?
