OLEConverter folder and winmail.dat


We are using Exchange 2007 SP1. We have seperate roles for Hub Transport, Mailbox and CAS.

I notice that there is a folder on the Hubs and Mailbox servers named OleConverter (under \\Exchange Server\Working).

There doesn't seem to be much explanation as to what this folder does, what OLEconversion is, and how winmail.dat fits into this.

Could someone expand?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
