Wow! Just Wow! @alexgrandh34 shows screenshots and tells support that he's using the Quickbooks Email service, NOT his email provider. Why is the answer to check the settings of his email provider?

@alexgrandh34 I had that same error this past week.... "error communicating" etc. I contacted support and they could not resolve the issue. They also suggested that I check my email service settings even though I told them I was using the quickbooks email. Then, they blamed it on Right Networks, our cloud hosting service. Right Networks is the biggest provider of cloud hosted quickbooks. I think by now they know what they're doing. Anyway, I checked with them anyway. Even though they technically don't provide support specifically for quickbooks program issues, they took me through several steps. Ultimately, none worked. As per usual, quickbooks support can't figure things out and they say it must be right networks. It's never been right networks.

I ended up waiting a day and the email service started working again. The support person from quickbooks was not able to contact anyone that could give them information on whether or not the email sending system was having problems.

Intuit, Quickbooks, whoever... up your support game.
