In Outlook 2010 we're trying to export GDPR confirmation emails. When selecting all emails and dragging them to a folder on the desktop, the mails stop copying at 129 items. I was not able to find a source why Outlook or Windows behaves this way.
It's also not possible to export to msg, only to pst, xls and Access. I did find however a lot of tools that can convert pst to msg but none of them were free.
Is there another way to do this?
