Have the same issue, I typically only send one email at a time, but encounter the issue where its "sent" but gets stuck in the outbox, then when you open outlook again it syncs and sends. Keeping outlook.exe open would be one workaround. Like Launch outlook at the beginning or end of the process. Another maybe to add a sleep or wait state of like 10 seconds at the end of the Outlook Send Mail VBO code (something to keep the outlook process open longer so syncing completes). But I have not figured out the syntax to add this successfully.
