HI,

I'm having an issue when trying to use the 'send mail' action in the Microsoft 365 - outlook object -

Internal : Could not execute code stage because exception thrown by code stage: The 'Content-Length' header must be modified using the appropriate property or method.
Parameter name: name

Any thoughts on how to fix this?

Thanks,

Jack

I noticed that the standard send mail action wasn't posting any 'body' I changed this action to 'post JSON and dropped in the JSON request. A simple change but worth noting. see below
