At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I'm sorry, but I cannot test this out with Office 365. They're asking for payment.
Would you mind checking if somehow the email is blocked or being filtered as spam? How about adding firstname.lastname@example.org or email@example.com to the contact list settings of the group email? If adding a contact is possible in the group email, please do and test the form again.
We're sending out the tests to the email in your last form ID so the problem might be related to the group email settings.
You can check the email logs in your account by following the steps from this guide: http://www.jotform.com/help/293-How-to-view-all-your-form-Email-History.
I added firstname.lastname@example.org to the group but that did not help. Email logs show status as sent.
I have forwarded this thread to our developers to see if they can check this to our backend. If there are updates, you should know it in this thread.
For now, please try using the individual email address in the settings. You can add multiple emails, up to 10 per settings in the form.
