Hi,
I need to switch away from using Outlook 2003 to something sensible like Thunderbird. But when I do I need to keep my mail archive, which is stored in multiple very big PST files, each organized in a folder-subfolder tree. It covers the time from about 1998 to now..

I have tried to find some working converter software available on line, but I have failed. Tried a few but they seem to lack the ability to handle the internal folders of a PST file.
One in particular show the full structure of the PST file I select for conversion so it looks like it would work. But in the end there is only a flat view of email in Thunderbird when I use the created MBOX file.

So now I wonder if there is some FPC code around that I can tailor to my needs? It seems a pity that the PST -> MBOX conversion should be such a problem....

The files are real big so I think I will need the 64 bit capability of fpc, which I have installed on my laptop.

There are several methods available in the market that help your file convert PST to Office365. You can also use the manual method but its lengthy process. After a long process, you will be able to convert PST file to Office 365. If you want to convert all the files at the same time, then you need to process any smart way. So you need a third party tool that can change all the files at the same time.

Use the tool that gives you the flat view, then create mail filters in Thunderbird to move messages to the appropriate folders, and then apply the filters to the existing messages. It may take a while to build the filters, but you'd want to do that anyway so that new messages go to the right place.

This becomes off-topic now (potential replies / follow-ups to fpc-other, please), but your suggestion implies that sorting into folders is always automated. That may apply to private e-mails, but most likely not to company / corporate area, so the recommendation may not apply in general at least.

Why is this repeated posting of advertising, that in no way answers the question of this thread, still allowed?
