Invalid Association trying to send e-mail

[macleod1021]

Hi,

We have CRM 3.0 installed on one server, SQL installed on another and Exchange Server installed on a third. All server OS's are 2003 fully updated. When someone tries to send an email from CRM Web, the email is not sent and they receive an error that says "Invalid Association the request association is not valid.". I attempted as the administrator and get the same error. I turned debug on and got the following error

Server was unable to process request. 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Web.Services.Protocols.SoapException: Server was unable to process request.

I searched here and the net and found an article that claims it's a result of anti-virus software on the mail server blocking port 25. As a test I removed the antivirus and tested. Got the same error.

I turned on full logging on the SMTP server and I'm not getting any events showing a connection attempt. I can also telnet into port 25 from the CRM server.

Any thoughts????

OK...I re-installed one more time using all of the same information and now it works. I have no idea :/
