Workspace Fabric missing from Windows One Lake Explorer

Hi vivien57 

Thanks for using Fabric Community.

You can follow the below troubleshooting steps:

1) Sync from OneLake: When you sign in with another account, the list of workspaces and items refreshes in the OneLake file explorer. If you navigate to workspaces associated with the previous account, you can manually refresh the view by selecting “Sync from OneLake.” Those workspaces are inaccessible while you’re signed in to a different account.

2) Workspace Names: Ensure that the workspace names don’t contain any special characters like “/”, encoded escape characters, or look like GUIDs. Workspaces with such names might fail to sync.

3) Windows Search: Make sure Windows search is enabled, as OneLake file explorer relies on it to start successfully.

4) Updates: Ensure that you’re using the latest version of the OneLake file explorer. Starting in version 1.0.13, the app notifies you when a new update is available, and you can follow the steps to update it.
