I have connected all my gmail email accounts to apple mail. I want to create a link between a specific email message inside filemaker so that when I click on the link in FM it will open the email message. I do not particularly care wether it opens the email in the apple mail app or in safari or inside FM. I know how to retrieve the message ID of the email in apple mail. I tried placing the message ID path preceded by the prefix "message://" inside a field in FM. Then I call the script OPEN URL with the field contents as a parameter. The script activates my email app ( Apple Mail ) but does not go to the specified message. Instead it just displays the last viewed email in Apple Mail. I tested the same URL path in a safari window , it seems to work fine. What am I doing wrong pls ?
