<h4 data-start="2470" data-end="2510">1. Incorrect Hosting Configuration</h4>
<p data-start="2511" data-end="2681">QuickBooks Multi-User Mode requires proper hosting settings. If the server or host computer is not configured correctly, other users cannot connect to the company file.</p>
<h4 data-start="2683" data-end="2722">2. Firewall or Antivirus Blocking</h4>
<p data-start="2723" data-end="2863">Firewalls or antivirus software may block QuickBooks from communicating over the network, preventing users from accessing the shared file.</p>
<h4 data-start="2865" data-end="2894">3. Damaged Company File</h4>
<p data-start="2895" data-end="3088">Corrupt or damaged company files can also trigger <strong data-start="2945" data-end="2987">Multi User Mode QuickBooks Not Working</strong> errors. A company file with integrity issues will not allow multiple users to work simultaneously.</p>
<h4 data-start="3090" data-end="3113">4. Network Issues</h4>
<p data-start="3114" data-end="3219">Network instability, such as slow connectivity or misconfigured routers, can disrupt multi-user access.</p>
<h4 data-start="3221" data-end="3262">5. QuickBooks Version Compatibility</h4>
<p data-start="3263" data-end="3444">Running different versions of QuickBooks on multiple workstations can cause <strong data-start="3339" data-end="3381">QuickBooks Multi-User Mode Not Working</strong> errors. Ensure all systems use the same version and updates.</p>
