Hi there, @UDNFinanceGuy.
I'd feel the same if I get the same error for how many weeks when switching from multi-user to single-user mode. I'm here to help get rid of the error message so you can get back to working order.
If the error consistently refers to a specific user, and that user is not actually doing a task in QuickBooks, you can follow the steps below:
- Have the user that’s referred to in the error close and reopen QuickBooks on their workstation.
- On another workstation, open QuickBooks. Go to the Company menu and select Users, then View Users.
- Have the user that’s referred to in the error sign out of QuickBooks on their workstation.
- Go back to the list of users. If the specific user no longer appears as signed in, you should be able to do the task without the error.
However, if the error appears on multiple workstations or on only one workstation, you can check out this article to learn how to fix it: Fix locked file errors in QuickBooks Desktop.
Just in case you want to know the tasks and features available you can use in single or multi-user mode, you can read this article for more information: Features available and tasks you can perform in single or multi-user mode.
Come back to this post if you have other concerns or follow-up questions about switching to single-user mode. I'll be right here to provide further assistance.
