6190, 816 | Company file locked or in use

What This Code Means

Where Users Usually See This Code

• Opening a company file stored on a server
• Switching into multi-user mode
• After a power loss or abrupt shutdown on the host

Why This Code Appears

• Stale lock files after a crash
• Incorrect hosting settings or multiple hosts enabled
• Permissions prevent lock file creation/update
• Network instability causing lock state desync

What Typically Happens Next

• Users are blocked from opening the file until lock state is resolved
• Host restart or official diagnostics may be required

What This Code Is Not

• It is not always a corrupted company file
• It is not an internet-only issue

Troubleshooting Checklist

• □ Confirm only one machine is configured as the host
• □ Ensure all users exit the file cleanly and restart host/workstations
• □ Verify the share allows creating and updating lock/temp files
• □ Check for power/sleep policies that interrupt host services
• □ Use the vendor’s multi-user troubleshooting flow for your product
