All my many folders in Post box were not exported into eM Client. Looking for advice on how to get them.
I had 14 folders for various types/years of email. I had to create those folders in eM Client then manually import to those folders. To import I had to add the .mbox extension to the files. The files in my case are in my user Library/Application Support/PostboxApp/Mail/… You’ll see for example:
Test with no extension and Test.msf. Add.mbox to the file with no extension. Then in import in eM Client choose .mbox import and follow the prompts. All my folders imported perfectly. FYI-With the .mbox extension change all the folders still worked in Postbox.
