If you run your own business and want to cut your expenses, you can use Mozilla Thunderbird, a free email client, to manage your company email accounts. As your business grows, you might decide to switch to Microsoft Office Outlook for a more powerful solution. Fortunately, it’s possible to export your email from Thunderbird and import it into Outlook, and you don’t have to purchase third-party software to get the job done.

Step 1Launch Mozilla Thunderbird.

Step 2Open the folder with the messages you want to export from Thunderbird.

Step 3Select the messages you want to export. Press and hold the „Ctrl“ key and click on the emails to select multiple items, or press „Ctrl-A“ to select all messages in the folder.

Step 4Right-click one of the selected emails and choose „Save As“ from the context menu.

Step 5Select a folder in which to save the messages as EML files and click „Select Folder“ to export the messages.

Step 6Launch Microsoft Outlook 2010.

Step 7Right-click the „Outlook“ folder and select „New Folder“ from the context menu.

Step 8Type a name for the new folder in the „Name“ box and click „OK“ to create the folder.

Step 9Select the new folder. It doesn’t contain any emails yet, so the middle pane is empty.

Step 10Select all the emails that you exported from Thunderbird. As you did before, hold „Ctrl“ and click multiple items or press „Ctrl-A“ to select all items.

Step 11Click and drag the emails to the middle pane of Outlook 2010 to import them into the new folder. The emails will appear in the folder after the import is complete.
