Hi there @The JBT Agency!
That’s very odd, the limit for uploads with OneDrive should be 100MB. What error message are you getting when the upload fails?
Also, could you send over a screenshot showing the settings and fields that have been selected in the Zap’s OneDrive action? Don’t forget to remove/hide private information like names and email addresses from the screenshot first. Asking for that as we can’t see into your Zaps, so having a screenshot will allow us to check whether there’s anything in the setup that might be causing the issue here.
Thanks for your assistance here, we’ll keep an eye out for your reply!
