Hi there, mchan123. I appreciate you performing some steps as well as contacting our Customer Care Team.
I've checked our records and have not found any users having the same problem.
Attachments added to transactions in QuickBooks Desktop (QBDT) are always added into the same folder as the company file. It'll create a link between them that allows the program to read and display the documents for you. If during the upgrade you moved your company file but didn't move the attachments folder, that could be what's broken the connection.
To fix this, let's ensure that QuickBooks is updated to the latest release. Once done, let's re-link the attached documents. Here's how:
- Open the location where your company file is stored and open the Attach folder.
- Open the folder with the OLD company file name.
- Copy and paste the contents of the Inbox folder into the Inbox sub-folder of the folder with the new company file name.
- Copy and paste the contents of the Txn folder into the Txn sub-folder of the folder with the new company name.
- Go to the Company menu at the top.
- Hover over Documents and choose Repair Attached Document Links.
- Click Open Company File Folder.
- Ensure that both the company file and the Attach folder appear in the window that opens, then you can close it.
- Click Repair Links.
Doing so will re-establish the connection. For more information about this process, take a look at this article: QuickBooks Document Center: FAQs and common issues.
When finished, try checking the attachments on a check again to see if you're able to view it.
Keep me updated how things go on your end. I want to ensure this gets resolved for you. Have a great day.
