How do I remove a PST from the outlook profile?(opposite of Addstore?)

[NipsMG]

I'm writing an add-in for outlook that monitors the PST Archives we're using, if they get too big, I want it to remove the current archive, rename it, and create a new archive.

Our IT manager is convinced that when people have PST files in their profile, it automatically loads a portion of them into memory on the exchange server, which is why I'm trying to remove the old one.(If this is NOT true, and someone can point me to some documentation on the contrary of this, then my problem is already solved)

I can create a new archive without issue, however, I don't know how to remove one programatically. Can anyone help with this issue?

Thanks in advance.
