Internet security levels are set too high.
You may also receive a message that intu-help-qb1 is an invalid address when trying to add it to your trusted sites. QuickBooks online features are designed to run with Internet Explorer security settings set to Medium. Settings other than Medium may result in pages not displaying or features working.

Note: It has been found that removing the Windows Component IE Enhanced Security Configuration has resolved this issue. If you are unable to edit the security level, contact your system administrator for additional guidance
