Migrated from Exchange 2010 to O365 Exchange P1 this past March 2014.
Prior to the migration we created .pst files some folders were so large we  had to break them into chucks.
Clients also used archives.
Turned off the Exchange 2010 services at that time, clients are all happy.
Today a client is stating that 2 years of his email is missing, the folders are there but the emails.
So I pull the tape (external drive) with all of the .pst files. I find this clients he email was broken down into 5 .pst files; four of the file work perfectly the 5 file wont open. When I try to access it whether by using the open command or import, it hangs Outlook 2013, stops Outlook 2013, looks for a solution and reboots Outlook 2013.

Note: Everytime I turn on the on premise Exchange 2010 server, a client's Outlook and file get totally jacked up. So turning the Exchange Server on again is really not a solution.

Question 1 is there a script or a way that I can just upload this data?
Question 2 is Question 1's answer is no, does anyone have any suggestions?
Question 3 is there a way to just grab the client mailbox (without turning on Exchange 2010) and uploading it directly to the O365 Exchange P1
Question 4 just like Question 3 is there a way just to grab the client's mailbox (without turning on Exchange 2010), I do have a test Exchange in a different domain.

Simon - I would love to use option B - a third party tool. I would purchase as I am not a fan of freeware. Can you make a suggestion, my internet search has left me with no tool that appears to work.

As I wrote, I don't make a recommendation for this particular task as almost all of the providers operate in the same way - using resellers who spam forums and newsgroups. I am not giving them any publicity.
I haven't used one myself at all, so cannot make a recommendation that way either.
