I am attempting to create an integration between Zoho forms and Outlook where Zoho form attachments are emailed upon form submission. Each time I try and test the integration, I get the following message Unable to send an email: The maximum request length supported is 4MB on some of the steps, but not all. Each time, it is a different step as well. Has anyone run across this error? I have done multiple searches and have not been able to find anything about this particular error. Thank you for your help!

Better practice is to save the attachments to an online drive (e.g. OneDrive, GDrive, Dropbox, Box), then include links to the folder or files in the email in order to avoid attachment file size limits by the apps or recipient email accounts.
