If a user is unable to e-mail or download invoices through AccountEdge Connect, it's possible that the issue is being caused by the attachment used for the logo on the invoice template. Removing or replacing the file used for the logo has been known to resolve this issue.

To check this:

1. Press the AccountEdge Connect logo in the top left of the screen, and navigate to the General Section
2. To the left, select PDF Customization
3. Press the dropdown arrow to the left of the "Set your company logo and styling" option
4. You can either re-select the image file to be used for the logo, or otherwise use the checkbox to "Display Logo in header" to remove the logo from the template altogether

The user should then be able to send and download invoices normally.
