Error in Forward an email (v2)

I am creating a cloud Flow using my own account when a new email arrives in a Shared Mailbox. All the processing works OK, but at the end I want to forward the email to others including myself.


I use Forward an email (v2) and use Message ID from trigger body.


If I provide Original Mailbox Address as Shared Mailbox then I get error as: The specified folder could not be found in the store.


If I don't provide Original Mailbox Address, then Flow keeps retrying against BadGateway.


To check if I have permission, I created another Flow, Manually Trigger Flow -> Get email (v2) and provide static message ID that I used in previous Flow and provide Shared Mailbox address under Original Mailbox Address - this works!


Further to check permissions, I create created another Flow, Manually Trigger Flow -> Send email (v2) and use To as my own email address and From as Shared Mailbox address - this works!


Can you please help in getting Forward an email (v2) working please.

I'm having the exact same issue. 


I have a flow that sends an automated email to a customer, I then use "Get Emails" to retrieve the message ID of that email. 


If a field isn't updated x amount of time later, it's supposed to forward the email. If I leave this field (Original Mailbox Address) blank: 


then it forwards successfully from my own email account. If I input the shared mailbox address the original item was sent from, then i receive the 'bad gateway' error.
