I am getting this error when trying to add a G-Suite account in Accounts and Import > Send mail as: (Use Gmail to send from your other email addresses)

If you are getting this error then a easy way to resolve this is as follows:

1. Enable 2-Step Authentication on the G-Suite or Gmail account that has to be added ( 

Turn on 2-Step Verification

 )

2. Create an App Password for that account  ( Create App Password )

3. Use the App Password instead of normal password in the password when asked during the Send mail as setting. 

This should solve the issue.
