We've been using Google Apps for Business for several years. We want to send out email from a group address instead of an individual one, e.g.
teamA@example.com instead of
JohnDoe@example.com with John Doe belonging to teamA. Previously it was all working perfectly.
However, starting form this year something went wrong. We tried to use
Settings > Account > Add another address to set up this functionality for new recruits. But, when Gmail asked the user to provide for authentication, we couldn't provide
teamA@example.com as the "username" as it's not an actual gmail account, and the authentication wouldn't pass. If we fill out
JohnDoe@example.com as authentication name, the setup can be completed, but then emails are sent with
JohnDoe@example.com in the "from" field, instead of
Did something in Gmail change? Or did we somehow mess up the process?
