Since switching to use OAuth authentication for sending email via Microsoft 365, the emails KashFlow is now sending via OAuth do not appear in the Sent-Items folder of our mailbox like they used to with SMTP.
They are dropped into the Inbox, which means we have to manually move them to the Sent-Items folder of our Accounts mailbox.
This used to work perfectly when we used regular SMTP auth before support for this was dropped by Microsoft (on completely reasonable security grounds)
