exchange auth error

lindajanedennis

I have tried multiple times to setup a new Outlook email to Thunderbird. I already have one setup and that's fine, but when trying to connect my new email account I keep getting the error

exchange auth error

I've tried everything to fix it.

The setup configuration all goes well, but then connection just won't happen. I've checked in Outlook and I have given Thunderbird permission but still it won't work.

I have the latest Thunderbird on my laptop. I have turned off the hub, but it still appears when I add an account. Sigh!

Please help!

- Make sure cookies are allowed in Thunderbird

- Do not use a VPN while attempting to authenticate your Google account

- Make sure there is no application running on your computer which is blocking local TCP port 80, e.g. a local web server
