I just modified the general.ini file by adding NeverCreateDuplicatesInMessageArchive=1
That was to solve the problem where I was getting a message asking if I wanted to copy duplicate messages to the archive. That message has stopped, but now when I sync messages my Windows Explorer crashes. Running Windows 10 32 bit.
I've looked at a few alternative products to MyPhoneExplorer but this is still the best out there! Hoping this can be resolved.
