I've got a VB dot net sub I'm thinking about reworking. It currently runs on a timer and checks for emails and their attachments and stores them in a database. The current code appears to be using Exchange EWS API Proxy to do this. The ExchangeVersionType is using 2007 and the biggest problem we have with it right now seems to be that if an email contains an image in the senders signature it crashes. We have to manually remove the image and resend the email to the inbox of the account it gets the emails from.

I just went through the code today to get a better understanding of how it works and noticed there are two libraries for handling emails - Exchange EWS and Exchange EWS proxy. I'm just curious what the major difference is between these two API's? Can I use either of them to do what I need to do?
