This morning I wanted to import my MBOX file to IMAP server but I was not able to do it. Then I searched on Google how to import MBOX to IMAP server. Then I found eSoftTools MBOX Converter Tool and I used this software and I got a very good result. Also, this software can import all types of files like PST, EML, MSG, EMLX, HTLM, and more. Apart from this, you can first download its free demo and try it which is available in.
