Proton Mail provides end-to-end encrypted email. If you are transitioning to Proton Mail from another email application and need the contacts you had stored in the other application, Proton Mail provides the capability to import contacts stored in a Virtual Contact File (VCF) or a comma-separated values (CSV) file. VCF, aka vCard, files usually have a .vcf filename extension while .csv is the filename extension for CSV files. To import such files, in the Proton Mail application, click on the Contacts icon on the upper, right side of the Proton Mail window, then click on Import Contacts, then select "Import from .csv or Vcard", then click on the "Choose a file or drag it here" button.
If you want to extract contacts from a
Microsoft Outlook
Personal
Storage Table .pst file, you can use the
readpst utility to extract the contacts from the .pst file. A command
such as readpst -cv -tc -o contacts_out your-outlook.pst
can be used where contacts out is the output directory where you wish
the utility to place the contacts (the output directory must exist prior to
running the command) and your-outlook.pst is the location and name
for the existing .pst file. E.g.:
alice@Wonderload:~/Documents$ readpst -cv -tc -o ~/Documents/contacts ~/Downloads/alice\@example.com.pst Opening PST file and indexes...
