I would like to have a document library created with incoming mail turned on. I've set this up, it is working fine. One thing I would like to do is figure out a way to categorize the incoming email (.EML file) as to whether it is an e-mail or an appointment? I understand an appointment is really just an e-mail but I was wondering if anyone can hint at a way to determine the difference. I've scanned over the email headers between the two but nothing is standing out. I know in the e-mail message, there is some typical text that is sent but I don't believe a workflow can open a EML file and read out the text to a variable.
My workaround will be to create a seperate document library and seperate e-mail address for meeting requests but I'd like to only have one e-mail address for ease of use for my end users.
