Is there a way I can convert a Linux Dovecot/Postfix/Roundcube Maildir folder into a PST file so that we can read it in Microsoft Outlook?
We have tried Python Scripts and logging onto the IMAP server but no matter what we set the usernames and passwords to with DoveAdm or Apache or however we set the folder permissions it will not let us login.
We eventually did this with Thunderbird
We downloaded the latest version of the import/export tools
Copied the users /maildir folder onto an exFAT disk partition and then just used the tools\import export tools feature to copy each mailbox into Thunderbird - we had to do the sub-folders independently but apart from that it was a relatively painless process. We then used an MBOX converter to get PST files from the Thunderbird files.
