AOL requires an APP password. Try logging into your AOL account, locate the security section and I believe there is a place to create an APP password.

If I create an APP password from AOL will I still be able to log into AOL webmail using the old password?

The two passwords server different purposes. Your old password will work on web; the APP password is a security aspect that AOL uses when accessing from a PC client.

Thanks.....do I need to have AOL create APP password for incoming and then another one for outgoing?

Before messing with an app password, why don't you try to set OAuth2 authentication for the outgoing server as well?

I tried that but there is no option under the outgoing for OAuth2

see attached screenshot

There are reports that changing the outgoing server will enable the OAuth2 menu item. It may not work for everyone though. See https://support.mozilla.org/en-US/questions/1359090

In case it doesn't work, you'd have to go the app password route.

Christ1,

Thankyou! that solution works......
