After the last update happened, I found I am unable to email receipts when a customer pays. I keep getting an error message saying server is down. How do I fix this?

Good morning, @saustinarm.

Thanks for reaching out to the Community. 

Typically, when emailing transactions in QuickBooks Online to customers, the error Server is down is frequently related to attachments on your transaction or the way your Company email information is set up. 

Since you've stated you have double checked the email set up and your customer emails, let's try additional troubleshooting steps to get this matter resolved. 

Let's check the PDF settings in your browser. I've included the steps for Chrome below. 

1. Open Google Chrome.
2. Go to the 3 vertical dots icon on the upper right, then choose Settings.
3. Scroll down and select the Advanced drop-down at the bottom.
4. Click on Content Settings. 
5. Tap PDF documents. 
6. Toggle Download PDF files instead of automatically opening them in Chrome to disable it.
7. Toggle the Adobe PDF Plug-in for Firefox to enable it. (If it’s already the case, Enable Chrome PDF Viewer and Disable Adobe PDF)
8. Log in to your QuickBooks Online account and try sending forms again

That should it. You can see further details about this process in Delivery errors when trying to email sales forms. 

Please let me know if you continue to have issues emailing from QuickBooks. I'm always around to lend a hand. Take care! 

I don't have Chrome, I have Safari (Mac book).  Is there a remedy for Safari?  Also, I had no issues prior to the change in the "new" invoice, what is causing the issue now.  I have done the uncheck PDF Attached option in the online delivery section.  I do not include attachments.  

I’ve got some information for you to get this resolved, @saustinarm.

Since you’re using Safari in your MacBook, I recommend reaching out to Apple support or an IT expert to check your Safaris’ PDF settings. They can help ensure everything is set up accordingly to prevent interruptions.

If you haven't tried sending or printing your sales forms in bulk, I recommend giving it a shot. This way, you can manage your tasks more efficiently. Also, you can customize your invoices to get the details you want.
