Barracuda & Exchange 2010
I set up a new Barracuda Spam Firewall Vx. The device is running but once I started pumping mail to it whenever users start up outlook they get an invaild certificate error which they do not get when running without the barracuda.
I too use Barracuda. The installation of this advice should not have any bearing on how the users connect to the Exchange box unless you are passing through the Barracuda to get to Exchange which is in no way necessary and I do not recommend it.

When the barracuda is not in the line I have no problems with my trusted cert which is Mail.mydomainname.com its only when the barracuda is involved that the issue comes up.
The Barracudda doesn't need to be in the line. All INbound mail can pass throiugh the appliance. Jsut connect to the Exchange server directly.

i did. On the firewall I pointed inbound traffic to the barracuda. I then added my domains to the list and pointed it to the IP of the mail server. Once I did that my clients started getting the cert error when they started outlook.
Right, for internal communication its not necessary to configure in line with Barracudda. However you can follow the above mentioned article to get it resolved

Yes I used that article to resolve the issue when I installed exchange originally. What i dont get is why the barracuda is getting involved with the outlook clients directly
You said: "i did. On the firewall I pointed inbound traffic to the barracuda. I then added my domains to the list and pointed it to the IP of the mail server. Once I did that my clients started getting the cert error when they started outlook."
This is not good and explains why the cert error is popping up.
Leave the way your Outlook clients connect to Exchange - alone.
Remove the PAT/NAT on the firewall as this will cause a problem.
Setup up the 'Cudda and simply tell it to forward mail for whatever domain(s) to the proper IP/Server.
Update your MX record from the old Exchange server to the new 'Cudda and that is it, you are done. No muss no fuss.
