Hello. I have DTPO 2.8.2.
I have started archiving email from Apple Mail and DTPO does a great job. However, I had started archiving a year or two ago in another app called Mail Archiver X. It will allow me to export those emails to MBOX, which I did successfully, but DTPO wasn’t able to read that file - the MBOX has 450 mb in it and DTPO “opens” the MBOX file and sees zero emails in it.
Any other suggestions? I have attached a screen shot from the export options dialog from Mail Archiver X with all the formats I can export to.
