Outlook send mail behavior with shared mailboxes

- Adding the shared mailbox as additional account should work. You can also configure a separate profile with just the shared mailbox, though this method will require switching the profiles every now and then. If all else fails, just use OWA to access the shared mailbox?
Hi,
- Disable shared mailboxes from caching mode.
