brandon23ss I have gmail, and have used email with no issues when sending invoices/estimates for a year. All of a sudden this message appears, i have many invoices that need sent but cant. All my settings are correct i believe.
TerryJS I'm pretty confidant the solution will be found in this article http://www.ghacks.net/2014/07/21/gmail-starts-block-less-secure-apps-enable-access/ Not very hard to fix and, I'm sure it would rate an item in the FAQ for Express Invoice regards
