Earlier this year, I installed a new Exchange server and moved all mailboxes etc from the old to the new. Everything worked fine. However, I couldn't take the old one down, because it had a critical function in our business: Without it, customers can't place orders through our web site.
Here's why -- as far as I understand it after some investigation (am no good at Exchange or HTML code, have no documentation about the the servers in question, and no contact with the guy who set this up):
When somebody makes an order through our web site, a text file is placed in the Pickup directory on the old server. There are some code in the web site which (as I read it) says: Place text file [the order] in \\OLD\Pickup. Then two things happen: 1) The customer get a confirmation, 2) the order is placed in a mailbox (and the order disappears form Pickup directory.
If I change the code to say: Place text file in \\NEW\Pickup -- the order is put in Pickup folder on NEW Exchange server when a customer makes an order, but nothing more happens, it just sits there.
Now, I don't know what it is that makes this play on OLD server, but not on NEW. I've search for scripts and settings at OLD server and at web server, but found nothing. I've also tried to read up on Pickup folder as such, but it's still very dim to me what it is for.
Help much appreciated.
