Certainly,​‍​‌‍​‍‌​‍​‌‍​‍‌ if you are utilizing a reliable MSG to VCF converter that preserves the integrity of the data. Manual methods and untrustworthy software can cause files to be corrupted or can miss certain fields. I have done the conversion of multiple Outlook contact folders with the GainTools MSG to VCF Converter and the result was total accuracy. The tool is intended to perform batch conversion of MSG to vCard without any change or damage to your data. If you want to be completely sure, use the free demo version which allows you to check the speed of the conversion and the accuracy of the fields before making a purchase. It is a safe and convenient tool for anyone who wants to keep their contacts secure while ​‍​‌‍​‍‌​‍​‌‍​‍‌migrating.
