You say you log into her desktop and the emails “download” to her inbox. Try to be more specific. Tell me, when she “logs in” to her desktop, is her outlook already open, in otherwords by logging in, is she just in fact “unlocking” a previous login she never actually logged completely out of? I ask because this sounds like she has her desktop pc Outlook set to download to a personal folder, or PST. If that is in fact the case, then the mail will be delivered and downloaded to her desktop outlook and not show up in OWA or on any other pc. So if she is just unlocking a previous windows login then the email will already be there in her desktop’s Outlook. Check her account settings. If you want to be able to see the emails in OWA she needs to connect directly to exchange and not download to a pst or personal folder.
