Once I’d converted the Enron emails to a PST and loaded them into Outlook, I thought I was almost done with my quest to get them on my Exchange server. The last remaining step was to copy them to an Outlook folder that’s in an account that’s hosted on that server. With the PST conversion taking about a day, I assumed it would take a while, but after running for 6 days, it’s still only up to the B’s in alphabetical order!
ExMerge is an alternative way to import a PST onto an Exchange server. It only supports non-unicode files though, and has a 2GB limit, so that doesn’t work for the 5GB Enron data set. Another suggestion (Experts’ Exchange, so scroll down past the ads to see the comments) is to turn off cached mode and do File->Import from within Outlook. I’ve cancelling my current copy and so far this approach seems a lot faster.
