We are currently using Groupwise 7 product and are planning to move to MS Exchange. One of the concerns during it is about user's local archive data. One option is to move all the archive data to Online and then it can be converted to pst file through MS Outlook client. But this is not practical for us and would like to know if there is any tool available that can convert the local archive data directly to pst file without uploading it to the server Online.

Please guide.
