TL;DR
I exported a users .pst file from exchange server 2008R2
He moved to a new machine, and his old machine was toast, so it's gone, and unreachable
On his new machine, when I imported the .pst file, he noticed that he only has emails going back to a fairly recent date.
Is it possible that he archived the emails before that date (he doesn't remember, and wouldn't know if someone else did it for him), and they were removed from the .pst file, and put on the local machine?
If that's not likely, or not possible, what's another likely scenario?
I'm new to using MS Exchange, and I inherited this server right before we moved to Office 365.
For the most part, exporting pst files, and importing them has gone really well. However, we have one user who is having some issues. When I imported his pst file, he noticed that he only had emails going back to a certain, fairly recent date. He just changed computers, and we don't have his old computer anymore.
I'm assuming what happened (with very little knowledge of how exchange actually works), that before the date where he doesn't have any emails, he archived the emails, and that removed them from the pst and put them locally on his machine somewhere? This is absolutely a guess, and I imagine it is wrong.
Is that something that is possible, or is there something else that could have happened in this scenario?
