What is the recommended download format?
The Data Export Portal allows you to download email data in a variety of formats.
We recommend using Outlook for Windows if you use a PC and Apple Mail for Mac users..
We recommend the following format for each email client:
Apple Mail - MBOX for Emails and VCF for Contacts
Outlook for Windows - PST for Email and Contacts Import
Mozilla Thunderbird - MBOX for Email and CSV for Contacts
Please verify with your provider which formats they support.
