Question
How to import a PST file from Outlook to cPanel?
Answer
Webmail clients can't read the PST format. To be able to import a PST file to a cPanel email account, you need to convert it first to a usable format.
Alternatively you can import a PST file if you connect through IMAP to a cPanel email account via an Outlook client.
