I have not been able to find any good explanations of which of the following options to choose when exporting a full email account to a .pst backup (that would eventually be loaded as a data file on a different instance of Outlook).
Every result showing this, advises the first option, however I don't want to err on the side of data-loss and I'm doing a one time backup before changing mail servers. Which of the 3 options below are best for that?
Does 'replace duplicates with items exported' affect your actual e-mail account or just the exported .pst?
*The version of Outlook being used here is 2016.
