Cannot get Android BB Hub to send emails via Outlook.Office365 / Hotmail
I have an Android Phone (Xiomi Mi8) running Oreo.
BB Hub for Android works fine for Gmail accounts but any emails created in or replies to my Hotmail Account (Office 365) get stuck in the Outbox.
There is a brief "Sending" icon, then a Clock Icon and finally a red asterisk icon.
Nothing gets sent and nothing moves on to the Sent Folder.
I have seen a small number of references to this problem but no solution.
I have done all the usual uninstall / re-install / clear the cache in BB Services etc, but all to no avail.
I know I can do what I need directly in the Outlook App for Android - but not via the Hub, which somewhat defeats the purpose of it.
Can anyone help?
