Hi! My name is ***** ***** I'm happy to help!
I'm sorry you're experiencing this problem. May I ask, are you accessing your gmail through the website, gmail.com, or do you use an email client with your gmail account, such as Outlook or Thunderbird?
Ok. Have you changed your gmail password ***** this began?
If you try to send an email today, what message are you given?
Can you please try to send a message now and see if you have the same error? If so, copy and paste the exact message here.
Ok, last question. Is your Google account personal, or administered through a company?
Ok, yes unfortunately you will have to wait for a period of 24-48 hours before accessing email again, unfortunately. If it was was a company address there are ways around it, but free personal accounts are subject to the automated system. The good news is that if you have changed your password ***** male are should have further access to your account.
You are quite welcome!
