Syncing data from Exchange

[Smannesman]

I'm looking for some advice and although I'm not sure I'll get it here, it probably can't hurt.

First off, I'm not one of the programmers here, I'm here looking for some advice because they're too stubborn

I work at a very small company that uses a CRM solution that has been developed inhouse.

One of the programmers created a tool (in C#) that syncs all e-mail, calendar and contact changes from Exchange to our CRM and vice versa.

Now that is pretty neat, unfortunately for some reason it's made the Exchange Store it's running on ridiculously slow.

Since Blackberry is able to do the same thing without slowing down and/or crashing Exchange, I'm wondering if someone could steer me in the right direction to make our tool similarly fast.

Like I said, I'm just looking for some advice so if you can give me a clue where to look to improve our app I'd be very grateful.

If not, at least I tried.

You already have my thanks for reading this.
