Though QuickBooks is continuously working to fix its errors, at times, while working, you may complain about Gmail not working with QuickBooks. Though it is not an uncommon error, you need to do something to fix it. There are several email integration options on the QuickBooks desktop. The options include WebMail, Outlook, and QuickBooks E-mail. As a user, you work and prefer to use Gmail, so you select WebMail.
At times, a user might see an email like ‘Sign-in attempt prevented’ from Google when trying to sign in to Gmail in QuickBooks. The email states that the ‘app doesn’t meet modern security standards. The message in the mail can be of concern because it mentions that the security of the mail is under threat. But do not panic as the message is a mere reflection of the fact that an ‘app’ had tried to sign in to the Gmail account.
