In general the mailmover would do the trick and converts the sxmboxexp files into pst files. Anyway it needs to be purchased from the vendor and I do not know how much they would charge for it at least the evaluation licenses do really stop after 5 runs or so. Anyway the mapping setup is really tricky as well. And last but no least: pst is a proprietary format as well and can only be read by using outlook so far (or used with TB to import into any imap mailbox). I do not know if you need address mapping within the process of converting the data if so: "Happy mapping
" otherwise send me a PM if you have further questions.
Forgot one thing: mialmover supports afaik only omcpoutu dumps which are limited to the well know ~2 GB limit... (anyway sxmboxexp should work but I never run any tests with sxboxexp'ed mailboxes ony omcpoutu ones...). I know splitting the export might be an option as well but this is really hard to handle..
