Hi @lisagansner,

Some company file is mapped in drive E. If that's your case, you can look for your company file name (E:) in the list. Let me guide you how.

1. Go to File, then Open or Restore Company.
2. Select Open a company file, then Next.
3. Browse the location of your company file, and choose the company file with .qbw extension.
4. Click Open. Enter your user name and password when prompted.

Please see this article for details: Open a company file located on a remote computer. 

I'm also attaching our these handy articles for additional reference.

• Hosting your company data in multi-user mode in QuickBooks Desktop.

• Error H101, H202, H303, or H505 when opening your company file.

That should let you access your file. Please leave a comment anytime if you have other questions or concerns. We're always here to help. Thanks for visiting the Community today and have a nice weekend.
