I am trying to write a flow to do the following:
-
detect when an email arrives in a mailbox - this works
next have 2 parallel steps
2a. forward the email to an external mailbox - this works
at the same time
2b. Reply to the original email from a shared mailbox using "Reply to email (V3)" - this fails
At step 2b I am retrieving the Message Id from step 1
I am then using "Original Mailbox Address" to insert the shared mailbox address I want to send the reply from.
This is failing.
The error provides a link to https://docs.microsoft.com/en-us/connectors/office365/#shared-mailbox-support but I cannot identify why it is not working.
It complains about "ErrorInvalidMailboxItemId" but this is being retrieved.
The Connection mailbox has both 'Read and Manage" and 'Send as' permissions to the shared mailbox.
