It won’t let me log-in to the desktop version, it states user unavailable... ?

Hello there, deecee-ayrshiree.

For Desktop app, there's a couple of solutions that you can work on to resolve it. First is to reset the app by clicking on the Help menu then selecting Reset App Data. If you haven't tried it, you can follow this suggestion.

If the issue persists, uninstall and reinstall the app. Once done, get the latest version of the app from this page.

Also, if you haven't tried logging in to your Quickbooks in a browser, you can also use other supported browsers in QBO:

• Mozilla
• Google Chrome
• Microsoft Edge
• For Safari, make sure to use the latest one.

Also, you can check this article to learn about the things you can to if you can't sign in to your account: Get help if you can't sign in to your account.
