Need to export all TB folders & sub-folders & all their messages & attachments, to a single file that Outlook (currently using Outlook 2007) will import & that Outlook will use to create a mirror-image of the TB profile, inside Outlook. Current TB profile contains approximately 2,000 folders/sub-folders, with tens of thousands of messages/attachments, and size is about 26 GB. Using Win 7 Pro, 64-bit, with IE 11. TB is up-to-date.

If you have an IMAP mail account, the emails are kept on the server and you can use any email client to view them remotely.

Possible Options: Option 1: If you use IMAP in Thunderbird, then you can easily create an imap mail account in Outlook to see same folders and emails. No need to move anything.

Option 2: If you curently have a POP mail account or emails in 'Local Folders' mail account and the server allows you to use Pop or IMAP. In Pop account, Stop messages downloading and make sure you leave messages on the server. Create a new IMAP mail account for same account. Create the necessary folders on the IMAP account and then select emails in a folder, right click on highlighted emails and use 'copy to' from pop account to imap account to put emails back on server. Suggest you do a few at a time to start with and check they get back on server correctly. Then you can create an imap mail account in Outlook and hook up to see emails.

Option 3: You need to use a program that converts files. Thunderbird stores files in mbox format, but you can export emails in .eml format. Right click on email and choose to 'Save As', choose where to save the file, notice it is saved in .eml format. This tool is good for exporting alot of emails and saving in .eml in one go. ImportExporttool:

Right click on Folder and select 'Importexport tool' > 'export all messages in folder' > 'EML' choose where to save. Then you have emails in eml format.

then use a eml to msg converter. I located this: http://www.outlookfreeware.com/en/ http://www.outlookfreeware.com/en/product/all/OutlookConvertEML2MSG/#.U8j0TUCTI1c

then you can easily use drag and drop to get emails into Outlook:


Alternative: you will need a program to convert mbox to .pst, but you may have to pay. I cannot endorse nor give any comments on these products. I located them on google:
