So im stuck. Goal setup email to send to kindle. Read several post and help docs (to include the app doc page) on set. caveat im using @outlook.com email vice @gmail.com. But have it configure based on what i've found online (tried the alt as well) getting the following error when i try to test (aka test authentication).
Manually sent to my kindle via email, and kindle does receive (added to whitelist in amazon kindle list), so once i can figure out this authentication issue it will work.
Anyone who's figured this out, would be grateful for someone to say what i did wrong so it can be fixed and get it so i can send to my kindle via the app.
What i did.
see below for basic config for @outlook.com email in ABS and test (aka authentication) error i received
whitelisted email in amazon kindle list
manually sent via Thunderbird/outlook application on desktop, and successfully received on kindle
