Same issue here
I’m trying to retrieve emails from a shared mailbox I have access to and is mapped in Outlook.
I’ve tested against multiple inboxes and sub folders but all return the same error. Workflow works if I clear the Account field so that it retrieves the emails from mailbox of the logged in user.
Further testing confirmed if I launch Outlook using an alternate mail profile with the desired shared mailbox as the default, then the emails are successfully retrieved.
Is there any investigation into this regression from UIPath?
