I am currently using Mozilla Thunderbird to manage my emails, but now I need to migrate some important emails to Microsoft Outlook. The main requirement is to convert Thunderbird emails into MSG format so they can be easily opened in Outlook. My concern is that during the conversion process, I do not want to lose any email attachments, formatting, metadata (To, From, Date, Subject), or folder structure. I have tried searching for manual methods, but they seem complex and time-consuming, especially for a large number of emails. Can anyone please suggest a reliable and safe method or tool to convert Thunderbird emails to MSG format without losing attachments or data integrity?
