Does anyone need still need help with this?

 Yes, my unanswered forum post from some days ago:

 Hi Idris, yes. I have the MaxiCOM MK808. I can not use the email function. Any assistance is appreciated.

 I had same issue, couldn't set up email, wrong username or password.  Couldn't send email but could receive.  It used to work but it had been a while since I used my MS906.

 Can you share the instructions Chris sent to you?

  I have/had the same problem. After deleting my account and reinstalling it, same problem. I could not get past the screen where it states user name or password incorrect (although I was sure my PW and user names were correct) The fix is to go into your Google account (upper right corner of browser with a circle with the first letter of your  name), click on the circle> click "manage your account"> click "security" on the left side>select 2 step verification with your phone as a text> also select app passwords> and create a password for your mail app. Use this password in place of your normal Google password when setting up your email and it will complete the setup without any issues. No manual setup either, just use that password and the rest is done for you. I am not even sure if the 2 step verification is required but I did it 1st and then the app password and that immediately resolved my problem.

     Go into your Google/Gmail account (upper right corner of browser with a circle with the first letter of your  name), click on the circle> click "MANAGE YOUR GOOGLE ACCOUNT"> click "SECURITY" >scroll down to LESS SECURE APP ACCESS and turn it ON.

 First I could send my diagnostic on blue tube but now I can't why.

 Same problem

 I got this figured out.  Go to your google account settings and click on security. Here is a direct link
