Today I got Zapier plus the free "fmgateway" (connects FMS to Zapier) working with Outlook.
The best news is that since this is a single trigger and a single action , it's totally free forever at Zapier (as long as there aren't too many emails). Their paid plans are very reasonable also, if needed.
The fmgateway connector writes directly to the FMS tables using the action I chose. You pick the field names as you set up the "Zap" (a Zap is the trigger plus actions). All interactive. No Data API, no coding. I like coding, but heck, this was just too cool!
You can request a free invitation of the fmgateway here:
According to the company, this is totally free for any use.
Hope this info helps somebody.
