Well pretty simple. You say people are emailing you already. My suggestion would be to set up a outlook rule to have them move to a folder and then once a day download them all and then use a script to open them, get the information off of them and update your main spreadsheet. I've got a script to download all attachments from all mails in an outlook folder. It is at work but I can give it to you tomorrow. Once you have the files it is a pretty simple thing extract the information and update your spreadsheet through VBA. How you do this exactly depends on your structure.
