Send Mail doesn’t support Perform without dialog. The email displays on the device, and you can send it
manually. This does not apply to mail sent through SMTP.
As for desktop, if you use outlook with exchange, it's notorious for requiring external app authentication over and over again. The only way I've gotten around this is sending via SMTP (you can calculate the settings for different users/exchange accounts, exchange still supports sending via SMTP), or via a plugin (IE Productive Computing's Outlook Manipulator).
Thanks for the reply, Dave. I was thinking this might be the case.
Thanks for the (very thorough) reply, Mike. I was thinking the platform was standing in my way. I don’t believe I can use SMTP, I’m working in an offline (local to the iPad) copy of the database.
You CAN use SMTP in Filemaker Go. I'd highly recommend bookmarking the FMGO development guide I linked to above. in the quote I posted above from the guide:
This does not apply to mail sent through SMTP.
I would try it and see what happens. You can usually get your SMTP relay settings from your exchange administrator. We use hosted exchange (rackspace, intermedia) and have always been able to use our exchange accounts with SMTP outbound capabilities.
