On an Ubuntu box, I used the readpst command from libpst to convert a PST file to a series of mbox files. Upon importing a resulting mbox into ePADD, all the attachment filenames look something like this:
where ## is the sequence number of that particular attachment within the mbox.
In the mbox file's attachment file headers, everything looks appropriate, though I'm no expert:
Any ideas on why the Sample%20Addendum.doc filename is not getting brought over properly, based on the syntax of this header?
EDIT: More information -
I used a vagrant/VirtualBox machine with Unbutu 14.04. I can provide more specs if you need.
My process was:
1. copy the PST from a network path to ~/email
2. mkdir export and cd into it
3. install PST tools: sudo apt-get install pst-utils
4. readpst ../mypstfile.pst
It churned through the PST, creating an mbox file for each folder in the original mailbox.
The libpst used is this package: http://packages.ubuntu.com/trusty/libpst4
