I have been looking for such software on the Google Search engine that Exports my mozilla thunderbird mail to outlook mail without any problem. That's when I got eSoftTools Thunderbird converter software on the eSoftools.com website. The software is 100% secure so that there is no chance of malware and virus threats to come in any windows operating system like windows 7,8,8.1 and 10. The software graphic and user interface are very simple and amazing. The software provides 24*7 technical help. The demo version of the software also exports up to 25 emails from each Mozilla Thunderbird to Outlook and other convertible formats like EML, PST, MSG, HTML, EMLX, NSF, Gmail and Office 365.
