I'm trying to check for the organization id, per SF instructions, when processing an outbound message in a web service. I am comparing the org Id in the message to one I have put in the settings.settings file. However, the Org ID in the message has "EAI" appended to it. If the org ID in our Company Profile is 00D7700000033K0 the org id in the outbound messages is always 00D7700000033K0EAI. Why is the org ID never correct in the outbound message? Is it safe to just use 00D7700000033K0EAI in the settings file?
