This happens because Google wants to take over your e-mail service; in other words you must be using your Android or smartphone's e-mail app instead of Google's GMAIL App. There are two fixes to this problem, first is to download Goggle's GMAIL App and use that for email communication; and second is to ask google to allow 'less secure' apps i.e. non-google to access your e-mails (i know!) Here are the steps for the second option:
Allowing less secure apps to access your account
Google may block sign-in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safe.
Some examples of apps that do not support the latest security standards include:
The Mail app on your iPhone or iPad with iOS 6 or below
The Mail app on your Windows phone preceding the 8.1 release
Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird
Change account access for less secure apps
To help keep Google Apps users' accounts secure, we may block less secure apps from accessing Google Apps accounts. As a Google Apps user, you will see a "Password incorrect" error when trying to sign in. If this is the case, you have two options:
Option 1: Upgrade to a more secure app that uses the most up to date security measures. All Google products, like Gmail, use the latest security measures.
Option 2: Change your settings to allow less secure apps to access your account. We don't recommend this option because it might make it easier for someone to break into your account. If you want to allow access anyway, follow these steps:
Go to the "Less secure apps" section in My Account.
Next to "Access for less secure apps," select Turn on. (Note to Google Apps users: This setting is hidden if your administrator has locked less secure app account access.)
If you still can't sign in to your account, the "password incorrect" error might be caused by a different reason.
I fully agree with the submenu that should display, "resend" ; but I discovered recently that pulling the menu and selecting "refresh" or "update" (don't know the label in English) indeed try to resend the failed messages.
