0xCAA80000 outlook 2016 'You need internet for this'
Hi,
Situation:
I have Outlook 2016 (ProPlus) with 4 Office 365 accounts. Since yesterday I account is not connecting to Office 365 anymore, I get error code 0xCAA80000 'You need internet...
FYI for those above an newcomers - I had an issue similar to this with
0xCAA80000
api-c97d7c50.duosecurity.com
messages when the Duo security screen should have appeared for MFA approval;
deleted token similar to EMAILL above mentioned - except my fix was in \appadata\LocalLow\ instead of local appdata.
Specifically, "C:\Users\MeMyselfandi\AppData\LocalLow\Microsoft\Crypto\TokenBindingKeys\
and it was just a folder in there.
This worked after trying Windows updates, clearing IE / Chrome / Edge Cache, enabling TLS 1.0, 1.1 and 1.2 for Internet Options, multiple reboots, testing sign-in on another device (successful), testing other user sign-ins on troubled device (same error), even authorizing a bypass for Duo (it didn't care).

This helped me!! I think this is exactly what happend to my device. I have it with duo and right after I chose TLS 1.2 under internet options, it worked for me.
