Thunderbird emails over to Outlook 2007/2010 How

Question

  I have 2 computers here in the office that have Thunderbird install on them and my boss would like for them to be transferred over to Outlook 2007/2010 with out any data loss. Every thing I have read has inform me that there could be some data loss.
Is there any way to do a complete data transfer without lossing any data to Outlook 2010 without using express.

   The easiest way is the baby step route-- at least you will not need to buy any software (or load any malware).
   1. Get an IMAP email account somewhere.  The only free version I know of is through Google, although if you have a web server somewhere you probably can get an IMAP account there.  Set this IMAP account up on Outlook: it's easy to
do and both Google and Microsoft have help pages to walk you through it. If you need help, Bing or Google this subject, followed by either "site:google.com" or "site:microsoft.com" in the search box. Also, set this account up on your Thunderbird
mail client as well.  
  Now you should have both identical IMAP accounts set up, on Outlook and Thunderbird.  Make sure you have sync'd both to the server when choosing options, so your client computer and server both mirror one another.
  (Of course, if your Thunderbird account was an IMAP account to start with and not a POP account, you could avoid setting up another account and instead simply set that up on Outlook without any conversion, so I'm assuming you are inquiring about a
POP account in Thunderbird.  If you have an IMAP account in Thunderbird sync'd to the server, all you would need to do is to set that account up in Outlook, and all your mail will show up by itself, after a pause).
  2.  In the POP Thunderbird account, just drag all your folders from your old account over to the new IMAP account, which also exists on Outlook.  (I do this all the time by the way, move folders between various mail accounts that exist on
both clients.)  
So now all your folders will show up in Outlook on your new IMAP account and can be dragged, copied, deleted to any other Outlook mail account.  One caveat that people (me) sometimes overlook if new to IMAP: they still need to do .pst backups, even
though the server/client are sync'd.  If one accidentally deletes a file or a folder, say from a Unix type system, or corrupts files by some other route, it can still be lost--so back-ups are very necessary.
Any address books in Thunderbird will need to be moved separately, in an exported file.
Hope this helps.  I do stuff like this all the time by the way, it's helpful especially when I have to convert a very old program or 'can't get there from here,' to go to some intermediate destination.
