Thank you for posting here in Community, case450.

I appreciate you letting me know that you've tried running some tests in sending your invoices.

This error could be caused by different things. One potential cause is an application installed on your computer, such as an anti-virus or security program, that is hindering the ports that QuickBooks needs in order to send email through these web mail applications.

I recommend checking your ports, the following link contains information on this: Set up your email service in QuickBooks Desktop

Have you tried sending the invoices using Web Mail? Let me know as well if you're getting an error message. 

You may wish to consider contacting the Phone Support Team as they can do a screen share and look over your settings and troubleshoot through a screen share.

Let me know how this works. You can do so by replying down below. Thanks!

Have been sending invoices   and payment receipts with no problem using my AOL account. For security reasons , I changed my AOL account password because it had not been updated in almost a year. After changing my AOL password , I can no longer send invoices.  When I hit send ,I get a password request for the AOL ID. When I enter my new password  I get an "incorrect password error". I know the password is correct because I can log into AOl with it while I am using QB2019 pro .
I did the whole preference check out thing under send forms .  Aol settings are  User Id-  **** Server Id: smtp.aol.com  port: 25.  I have deleted and did a clean ADD. All attempts still get the password error. I have checked the []ssl and unchecked with no clearing of the error.

3hours reading support forum "fixes" and all say do the send forms update / verify current settings     As most post say NOTHING WORKS
Trying to be more secure by changing my password , now has me dead in the water as far as emailing invoices to my customers

Using  QB pro 2019, Win10pro,Office 365, Windows edge browser, Win defender security 

I repeat EVERYTHING was working ok until I changed the AOL password, Now QB will not accept it 
 

Hi there, SirFrank.

Aside from what you've already tried, you also need to generate an app password. This is required by AOL since you're accessing it via a third-party email app and the new password isn't recognized by QuickBooks yet.

Here's how:

1. Go to AOL's account security page.
2. If prompted, sign in to your account.
3. Select Generate app password.

   Note: If this option doesn't appear, you'll need to enable 2-step verification.

4. Select the app you use from the drop-down menu.
5. Select Generate.
6. Follow the instructions provided to use the app password, then select Done.Note: You can also stop the app password by managing it.

Let me also share these articles for more details: 

• QuickBooks Won't Accept My Web Mail Password
• Add two-step verification for extra security

Quick books was not on the list of apps ,so I used the ADD feature to add QuickBooks. It generated a 16 digit (xxxx xxxx xxxx xxxx) .

Went to QB and tried to send a test invoice to myself.  Same thing , password error.  So I entered the app password that AOL generated.  password error .

Frustrated , I deleted the Aol ID under send forms and added a new Gmail id setting Id , it auto had SMTP settings in a drop down box for gmail. hit create. Then it sent me to log in the intuit site, but it loaded my very old  (2013) user ID  and would not accept the old password that we pulled from our password log listing ( last created/changed may 2015)  the intuit log in  would not let me enter my current ID. The 2013 id from intuit payroll was locked and could not be removed from the box 

So frustrated from this right now, I wish I never changed the AOL password for security. 

As the old adage goes "if it's not broke , don't fix it"...….. how so true here

Sending good vibes to you, SirFrank.

I'd be happy to help you set up an email so you can send invoices via QuickBooks Desktop.

Gmail may be blocking sign-in attempts to your Google Account. You'll have to enable access for less secure apps and turn off 2-step verification for QuickBooks to have the right permissions to send emails using your Gmail account.

You can follow the steps in this article to enable access for less secure apps. Tip: Your Domain admin can lock less secure app account access. Learn how to allow less secure apps to access your account by following Allowing less secure apps to access accounts. Also, turning off the security feature to enable this on your Gmail account.

The following articles are good references:

• Set up email service.
• QuickBooks won't accept my web mail password.

If you're still getting the same issue, you can reach out to our QuickBooks Desktop Support to have this investigated.

1. Within your QuickBooks Desktop, click Help at the top menu bar.
2. Click Contact us.
3. To route you to the correct support expert, we need to know what type of question you have. Give a brief description of your issue and click Continue.
4. We’ll provide you a few options. You choose which one is best for you.

You can always get back to me if you need more help in setting up your email in QuickBooks. I'll be around to help.

No matter how I try to set up a NEW email address when it sends me to the intuit site, it tries to use an old intuit ID from 5 years ago . It will not accept the password. So you click on FORGOT PASSWORD, it sends you to a security question page and does not accept the answer to the security question
You are virtually locked out from doing any fix
I have invoices that need to be sent out and they are backing up

Like I said .. EVERYTHING WAS WORKING UNTIL I CHANGED MY AOL PASSWORD FOR SECURITY UPDATE. now NOTHING works to fix the email send forms settings in QB

this has to be a big problem because the QB forum is inundated with how to fix this issue requet and all you guys give is this same boiler plate answer that DOES NOT WORK

I set up an app password in aol. it generated a 16 digit code in the format of xxxx-xxxx-xxxx-xxxx. When it does this , it also has the following text

How to use this app password
1. Go to the settings section of your app ( this would be the send forms - correct?)
2. Find the screen where you enter your AOL account username and password ( send forms never ask for a password so how can you do this?)
3. Copy the app password above and paste it into the password field ( there is no password field)

So , what is one to do?
