QuickBooks must operate in single-user mode when performing a number of tasks including:

• Creating Portable Company file

• Rebuilding Data

• Copy Company File

• Importing & Exporting

• Set Closing Date

• 1099 Wizard

• Change Bank Feeds

• Schedule Reports

• Work with Accountant's Copy

• Payroll Setup

• Changing Company Preferences

Sometimes folks forget to revert to multi-user mode after performing single-user tasks. Click File, then "Switch to Multi-user Mode" or vice versa get yourself to where you need to be.
