Mikeone,
Thanks for your reply. I don't have a problem getting to the settings pages in Aqua Mail to check the various settings. However, I'm not able to see different options (such as clicking on Authentication). In my other Aqua Mail Email account (also coordinating with Gmail), it appears the options on the settings pages seem to be a little different....
Kostya,
I logged into the myaccounts page at Google. I went into the Sign in and Security sections and found no error notifications. I also did a complete Security Checkup. Again, no problems. So, I'm still confused.
Thanks,
