Emailing receipts to QuickBooks Online stopped working. I get a response that it can't read the format. Did the ability to forward emails with attachments stop working?

I’m glad to help and provide information about our supported attachment file types, @jeff191.

At the moment, the SMIME.p7s file format (a digital signature that is sent alongside a digitally signed email) isn’t supported in QuickBooks Online (QBO) attachment types. Thus, you’re prompted that the program didn't recognize it. QBO only supports the following to protect the security of your company:

• JPEG
• PNG
• DOC
• XLSX
• CSV
• TIFF
• GIF
• XML

Check out this article to learn more about attachments: Add or delete attachments in QBO.

You may consider converting your file to get it added. You can visit our Apps Center or Apps menu within your QBO account to find a tool that works best for you.

Here’s how:

1. Go to your Apps menu.
2. Enter "Converter” on the Search field, then select an app.
3. You can click the Overview, Pricing, Reviews, and FAQs to view the details.
4. Select Learn more at the top, then Add app or directly tap Get app now.

I’m also adding this resource to get troubleshooting tips about sales forms, especially resolving email bounces or transactions that fail to deliver: Fix undelivered invoices in QuickBooks Online. It helps make sure customers receive their invoices and pay you on time.

Thanks Madelyn.  I figured out that my Apple Mail account had the “digital signature” feature turned on, and that was adding the smime.p7s  file to every outbound email, and that file attachment was unable to be read by QBO. It was the attached invoice or receipt that was the problem - it was the digital signature file.    Once I turned off that feature, I was able to successfully send emails to QBO and have it parse the attachment to create an expense.   Thanks for your quick response.

I'm happy to hear that you're able to figure out your concern, jeff191.
