I added three users yesterday to the workspace. Post adding, all our emails worked and we received everything correctly and properly. However, after my third user logged in today, two of my users lost use and couldn't send or receive emails internally. They can't seem to send to others within oour workspace, nor can they send outside to other workspace users. We are able to receive emails from outside the workspace though.
Me, as admin, I have full access with no issues, and can receive both internal and external emails. What's going wrong?
