Send email from shared mailbox with embeded connection


I have a flow that sends an email from a shared mailbox see below. I have added myself as a member of the shared mailbox and selected to use my connection in the fpermissions not provided by run-only user as the user isnt a member of the shared mail box. 


I keep getting the following error but im not sure why as im asking it to use my connection. Can anyone see what my issue is?


Unable to process template language expressions in action 'Send_an_email_from_a_shared_mailbox_(V2)_2' inputs at line '1' and column '2700': 'The template language expression 'json(decodeBase64(triggerOutputs().headers['X-MS-APIM-Tokens']))['$connections']['shared_office365_1']['connectionId']' cannot be evaluated because property 'shared_office365_1' doesn't exist, available properties are 'shared_office365users, shared_approvals, shared_sharepointonline, shared_office365, shared_sendmail'. Please see for usage details.'.

Re: Send email from shared mailbox with embeded connection

Hey @Barber_Chris 


What is the trigger that you are using for this flow? I have seen such an error very common with the powerapps trigger and the fix for that is removing the flow from the PowerApps control and then adding it back (as the step that you created mioght have been added after registering the flow on the powerapp control and it is pointing to a previous version). Similar issues have been observed with the File system based connector. 


If it is not powerapps based trigger, you might want to try to export the flow and then import it back and provide all the relevant conenctions during the import and check if the issue still exists. 


Hope this Helps!
