Using Outlook for iOS for personal email and calendar management
The best alternative I have found is to use the Edge browser app on my iPhone as it has great read aloud page features...
- I go to Outlook.com in the Edge app
- Select an email and at the bottom right 3 lines I select 'Read Aloud'
- My preferred voice is "Christopher (Natural)". You can select your preferred voice of course and there is a long list to choose from. You can get to voices once it is reading, just click on the voice options icon (upper right).
It can be glitchy at times; either Edge not loading Outlook or it just not read aloud at all, but reloading the page or killing the app helps.
Also - it reads URLs! which I hate (Cortana always pleasantly said "Theres' a link here".
I hope this helps and hopefully MS will restore Play My Emails with Cortana!!
