User2 can't open QB unless Admin user closes company first

Welcome to the Community,@MMajor.

Let me share some insights on why user two can only open QuickBooks Online Desktop if the Admin user closes the company first.

We first need to configure the setup in a multi-user environment so all users can access the file simultaneously.

The setup requires adjusting settings in QuickBooks Desktop, Windows, and your server.

Step 1: Set up QuickBooks Desktop

On a multi-user network, one computer hosts your company files. This is your server computer. Computers that connect to your network but don't host your company files are called workstations.

Step 2: Set folder permissions

Follow the steps to set up folder permissions on your server computer. Make sure the folder with your company files has permission to be on your network.

Step 3: Install Database Server Manager

If you follow the steps in Step 1, QuickBooks also installs QuickBooks Database Server Manager on your server computer. This tool lets you share your company files with other computers over your network.

Make sure QuickBooks Database Server Manager is installed.

Step 4: Adjust firewall and security settings

Follow the steps to configure your Firewall and Internet security settings so QuickBooks and Database Server Manager can run on your network.

Step 5: Set admin rights

Make sure the user account you use to sign in to your server computer has Windows admin rights.

Also, make sure the Windows user account for Database Server Manager has admin rights.

Step 6: Use Database Server Manager

After you install the Database Server Manager, follow the steps and use it to scan the folder that holds your company files.

Step 7: Turn on hosting

Now that you've set up everything outside of QuickBooks, all you need to do is turn on Multi-user Access on your server computer. Your server computer should be the only computer with this feature on.

Step 8: Install QuickBooks on a workstation

Now that your files are hosted over the network from the server let's install them on your workstations.

For more detailed instruction, you can view this article on installing QuickBooks Desktop on a server to learn how to install and set up QuickBooks Desktop on a server so computers on your network can access your company files.

I'm also adding these helpful modules you can browse about how to access QuickBooks Desktop remotely from a host or server computer. Also, access folders in the multi-user mode; the folders need to have the right Windows permissions:

• Open a company file on a remote computer.
• Set up folder and Windows access permissions to share company files.

Still have questions about your concern, users can't open QuickBooks Desktop unless the admin user closes the company first? Don't hesitate to reply to this post. I'll gladly answer them for you. Take care and have a great day ahead!
