016-0507 error message

[Coolpro]

Hello
I am getting this error message when I do scan document and send by email. I didn't have problem in the past but just started recently after taking software updates. Please let me know how to resolve this problem.
Thanks

016-507 is an invalid login, usually due to an invalid response(logs in, but doesn't understand the response and quits), which is what would happen if the server uses a protocol the printer doesn't support. If that is the case,try a firmware update to get whatever update may be needed, else SMTP2Go should work.

Of course you may have just changed the password for the account the printer is using, or enabled 2 factor authentication or something on the account, but if nobody changed anything, it will have to be a server side change that maybe updating the firmware will fix

So I just discovered that I have to turn on features in my Google profile settings " less secure app settings" and work charm. I also upgraded my printer software as per your link.
Thank you very much.
