I am building a simple flow: when shared mailbox receive an email, trigger a reply to the sender.
Here is the reply action
Here is the error I got
As of May 6, 2020, shared mailbox support was added for certain operations with an optional 'Mailbox address' parameter, allowing you to specify a shared mailbox address for your operation to access. If you were using this operation prior to May 6, 2020, you will need to explicitly update your operations to specify the shared mailbox address. Please follow the Office 365 documentation for more information: https://docs.microsoft.com/en-us/connectors/office365/#shared-mailbox-support
I don't quite understand this. What did I do wrong?
