Import Thunderbird to Outlook – How to Avoid Common Problems that Otherwise Upset Many!
Import Thunderbird to Outlook Mac/Win
Whatever the reason to move to Outlook Windows from Thunderbird Mac may be, you need to face the data migration problem that is coming your way. Shifting your services, including a software email client, is not always easy. You may have to get used to the new interface, new style of working, and dozens of other changes. But the biggest challenge of all is how to move the data that was stored on your earlier client to your new one.
In this case, it is about importing Thunderbird to Outlook. And since both clients not only use different files to store data, they also run in different operating systems, this data migration can be difficult and tricky. There are no official features from either Windows or Mozilla to offer users to do this without relying on third parties.

There are indeed few manual methods you can employ. Like, getting all your data to a new email server and then syncing it from server to Outlook. But such manual approaches have their limits and could even lead to data loss. It is always recommended to stay away from trying to migrate data manually, especially if the database is huge and you have sensitive information in your emails.
Today we are talking about one very professional tool that can help you do this correctly and avoid common problems that could even upset top experts in email migration.
First, you need a file converter that can take the contents from Thunderbird files and then convert them to PST file, which is the native format for Windows Outlook. But while you dig for the files in Thunderbird, there is high chance of missing something, and this method too is also partially manual.
