Over the years we had a few repair and rebuilds that did fix errors (data issues) but they did not happen often. This did not improve the send form issue.  At the end we had issues of lost data which prompted the transition to a windows computer. 

I've run the QB Tool Hub several times and nothing gets rid of the error.

The damage is too severe. Consider purchasing a third-party file repair service.

I'm having the same problem.  So frustrating and time consuming.

Hello Fellow QB users and staff,

Since calling in doesn't help since they just go over the exact same things I have already done myself or they read off a how-to guide that I have already done or could have just read myself online, and end up just wasting my time, I just started the process of troubleshooting myself. Since I have previous IT support background, so I have went through many steps and scenarios to try and find where the issue lies. After updating QB desktop enterprise, running the QB tool multiple times, changing email address, changing email providers, updating DNS on the domain for the email, making sure all emails are good and active, I lastly started running my invoices and statements in smaller batches. What I have discovered is the smaller the batches the faster they get sent out since the queue is not too "heavy of a load" with all the invoices that get generated and waiting to be sent out. I noticed by doing this I can get closer to 100 at a time before QB desktop crashes. After I am through with all 2k of my invoices I then start running the monthly statements. I noticed if I run a large batch of 200 of statements they send very quickly without any issues at all. I think my issue is with the invoice template we are using. I think there is a corruption within the template that is being used. 

My next step is when I am able to find the time I am going to switch one of my larger invoice groups to a new invoice template before I run them, then see if they can be sent without QB desktop crashing. This make sense since one of the errors says "QB can't complete the current action due to a missing component. Download and run the Print and PDF repair tool." Even though I have ran that tool may times their tool does not fix the issue. (Note: Not the only error message I get) I think the only way is to manually update each memorized invoice. The bad part about this is that I have to manually do this one at a time for 2k customers.

After I get through this and do my due diligence with testing I will post back here again with my findings. I hope I find the resolution to get this fixed and to be able to share with so many of other QB customers that are in the same boat in hopes to get this resolved for many of us, and QB support will have a solution to help their customers who reach out for their support. After dealing with this issue for over 4 years and QB support never able to help me I hope that I am able to find resolution. If anyone test this theory out before me, then please let us all know and reply to this thread.

Side Note: In my troubleshooting I have discovered a print que for POs, Sales Orders, Credit Memos, and Etc. that have been piling up since 2014! Took me awhile to clear 6,172 of them! I just had them print to PDF, but instead of saving I just cancelled out of the box so QB thinks I printed them off. If you try to do them all at once, then your QB will probably crash, so you may have to manually check 100 at a time to get them cleared out. This didn't help with my email issue, but something to put into consideration for QB file size.

@QuickBooks can you PLEASE have the capability to run our print and email queues in pages or groups so we don't have to manually click one at a time. About every program out there has that capability, so I don't understand why your programs lacks that simple basic feature. The email issue wouldn't be so bad if we had this function within your system.

P.S. Sorry for any grammar, punctuation, or spelling errors. I have too much to do and not enough time to do them, but I wanted to get my finding out there, so I typed this up quickly to share. Thank you for your time.  

I understand the importance of sending invoices seamlessly, Jgainok. Please know I'm committed to helping you resolve the crashing problem when you attempt to email invoices in QuickBooks Desktop (QBDT).

First off, we can run the Verify/Rebuild tool to detect system errors or damaged data and refresh the company file. Before performing this process, please create a backup copy of your company file so that if changes occur, you can restore and undo it easily.

Here's how to verify your company data:

1. Go to the File menu.
   
   
   
   
2. Click on Utilities.
3. Select Verify Data. 

Then, to rebuild the data:

1. On the top menu, choose File.
   
   
   
   
2. Select Utilities.
3. Click Rebuild Data.
4. Hit OK if you receive a prompt to back up your company file.
5. When you get the message that Rebuild has completed, select OK. 

For detailed steps, refer to this article: Verify and Rebuild Data in QuickBooks Desktop.

If the problem persists, I suggest using the QuickBooks Tool Hub. However, if you've already performed all the troubleshooting steps mentioned above, I recommend contacting our Live Support Team.

Moreover, I'll share this resource to help you record invoice payments from your clients: Invoice payment.

If you have additional questions about managing invoices in QBDT, add a reply to this thread. I want to ensure you can carry out your tasks in the software smoothly.
