Credentialing error

Let's try resetting your email up, Acetesting.

This helps the system to refresh your email connection. I've got the steps on how we can do this:

1. From the Edit menu, select Preferences.
2. Click Send Forms.
3. In the My Preferences tab, select Web Mail.
4. Select your provider from the drop-down and enter your email address.
5. Select the Use Enhanced Security checkbox and select OK. 
6. When prompted, sign in to your Intuit account.
7. Your webmail provider's login page will display. Sign in and select to grant Intuit access.

If the same thing happens, let's check if the antivirus has blocked outgoing emails. Here's an article for more information: QuickBooks is unable to send the email since your antivirus has blocked outgoing emails.

Let me know how these steps work on your end. Stay safe!

Thanks for the reply but that did not correct the issue since I have already tried that, besides, there is no Enhanced Security checkbox.

Any additional help will be appreciated. 

I have been having the same issue every month when I need to email out our clients monthly invoice. 

Has anyone found a solution?

I have tried everything I can think of and have even googled how to do it and tried those suggestions as well. Nothing fixes it.

Let’s get this resolved so you can email out your clients an invoice without having any issues, @KimballPoolsCorp.

Before I share other troubleshooting processes here, have you tried the steps provided by my colleague above? If not yet, you can follow it first. 

Otherwise, we can run the repair tool in QuickBooks Desktop. Utilizing this tool helps fix common errors right away so you can get back to business.

Here’s how you do it:

1. Backup your company file first.
2. Restart your computer to makes sure there are no programs that may affect the repair.
3. Open the Windows Start menu, then select Control Panel.
4. Click Programs and Features, then Uninstall a Program.
5. Select QuickBooks from the list of Programs, then Uninstall/Change.
6. Hit Continue or Next.
7. Select Repair, then Next.
8. Once it's done, select Finish.
9. Update your QuickBooks to the latest release also, so you have the most recent fixes and security updates.

Once done, email a test transaction to yourself to verify. If the issue persists, follow step 2 and the rest of the instructions in this link to fix webmail password issues.

I’ve also added a reference here in case you want to personalize your emails to customers and vendors.  QuickBooks allows you to create an email template with customized subject lines and email bodies.

Please get back to this page with updates on your email situation. I’m always here determined to find a solution for you.

I am having the same issue when I try to send out invoices at the end of the month.  This has been happening for the last several months, yet before that, never had this issue.  One workaround I have found is to simply wait.  This appears to work.  Don't click OK, try waiting 5-10 minutes, re-enter the email password in the open window that says "Incorrect credentials or gmail settings."  Its a temporary fix.  I installed a new copy of Quickbooks on a new computer (fresh install) and still this issue is happening.  I am having this trouble with a yahoo email account.  I wonder if it has to do with yahoo and maybe if I switched to gmail this problem may go away.

I appreciate you for sharing a workaround on the Community page, @deerhill.

You can definitely try to switch to Gmail, as you suggested. Before that, have you checked or review your security settings in Yahoo? If not yet, you can follow these steps:

1. Go to your Yahoo Account Security page.
2. Turn on the Two-step verification and Allow apps that use the less secure sign in features.
3. Go back in to QuickBooks and email yourself a test transaction.

Otherwise, you may continue to switch and perform the following process found in this article to fix webmail password issues in QuickBooks Desktop.  

In case the issue persists, you can reach out to our Technical Support team to furtherly check this matter. They have tools that can determine the root cause and able to provide an immediate resolution. Our supports can also request an investigation if necessary. 

Please know that they’re available from 6:00 AM until 3:00 PM PT on Saturday and most open during weekdays starting 6:00 in the morning up to 6:00 PM. Here are steps to contact them:
