eM Client crash on import of *.pst file

I’ve imported my previous .pst files (both current and an archived) and in both cases eM Client crashes during the import, it does import a few of the messages, but I’d estimate about 10-20% of the total. The dates appear to be totally random bringing messages from 2009 right upto 2020, The same happened when I did the initial install too. I assume there is something in the .pst file it doesn’t like? Any ideas how to get the full file imported?

You might want to try importing just sections of the pst file. Do one or two at a time and see what happens.
