So i'm in the process of migrating a companies email from onsite exchange server to Office 365. I've set up all their mailboxes but now I need to import their .pst files from their local machines to Office 365 and I have no fucking clue how to go about this. There's a tool called PST Capture by MS, but it only works on 64bit OSs from what i'm reading and the company has only 32bit OSs.
I'm a complete noob when it comes to exchange and just learning by being thrown in the deep end, anyone dealt with this before or have any knowledge about how to go about this process?
