The setup is a user that has a laptop with Outlook 2010. We have Outlook hosted by Sherweb. The user that has a large number of emails (40,000) in a single Inbox subfolder. (I believe) Having such a large number of emails in an inox is slowing the users laptop down and I want to start moving old emails to a seperate pst file on a machine on our network.

The problem I have is the user needs to be able to search all 40,000 emails. Right now he can can search do a search on the single subfolder. I would like to be able to move some of the emails to a seperate pst so I can compact the Inbox and still give them a 'one-click' search function that is still fairly quick.

I don't think the 'Search All Outlook Items' is the soltuion because this will search all outlook folders -- sent items, other public folders.

P.S. I'm not a expericenced outlook administrator, so there may be some assumptions in my questions that are wrong. I have no problem with somebody showing the error of my ways.
