Outlook always tries to print attachments even when none are selected

Circumstances:

You have an email with at least one attachment and choose to print only the body of the email.

Result:

Outlook tries to print the attachment and either gives an error or prompts for an action.

Cause:

'Print Attached Files' is selected in the Outlook print settings.

Solution:

Follow the steps below:

File-Print and choose Native Print

Un-tick this box and click ‘Preview’

You can also make this change in the registry but Outlook must be restarted to take effect in this case.

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Printing

Set ‘Print Attachments’ = 0

This could be set via Group Policy.
