Dear,
So I get this error, ErrorItemNotFound, when running "Forward an email (V2)" trying to forward a message from a shared email.
I can access shared email via outlook, so I guess permissions are ok... that's my guess.
Message ID was obtained from trigger When a new email arrives in a shared mailbox (V2).
Can't figure it out what is wrong...
any ideas?
This seems ok...

"code": "ErrorItemNotFound",
"message": "The specified object was not found in the store., The process failed to get the correct properties.",
Thanks for your help.
