It's great to have you here in the Community, John. I'm here to share some information about the multi-user mode in QuickBooks Desktop (QBDT).

If you set up folder sharing and map the network drive correctly, using the dedicated hosting mode won't pose any potential danger.

The only issue I can see for now is that you are using a discontinued version of the product. This may cause errors in the setup when the system asks you to update the product in the future.

To avoid any issues, I highly recommend seeking assistance from an IT professional to expedite the setup process.

Additionally, please refer to this helpful article when you encounter an error when switching to multi-user mode: How to fix Error H202 and H505.

Please don't hesitate to reach out to the Community if you have any other concerns about the multi-user mode in QuickBooks. We're always here to help you in any way we can.
