Getting error in Microsoft flow using SMTP.

Question

Getting below error while creating a flow.
authentication failed. Please check your connection parameters. When you use 2-step verification, connector may be blocked from accessing your account. If this is a case , please try to create and use an app password. Otherwise , turn on access for less secure apps.

Hi @Microsoft Q & A

Are you using this: Option 1: Authenticate your device or application directly with a Microsoft 365 or Office 365 mailbox, and send mail using SMTP AUTH client submission

Set-CASMailbox -Identity ******@contoso.com -SmtpClientAuthenticationDisabled $false
