Best method to migrate Thunderbird to Office 365
This question is common for Thunderbird users to somehow convert Thunderbird mailbox to Office 365. However, despite many measures, there is no sure result. For an error-free and easy solution, I would like to suggest the adoption of MailsDaddy Thunderbird to Office 365, which imports all data in full, keeping the mailbox structure without compromise. This is the most in-demand tool online. I have already used this utility on large mailboxes; it is 100% safe and efficient.
