    .Overview folder in the workspace containing the relevant geodatabase, this may corrupt the mosaic dataset.
    1. Launch ArcCatalog or ArcMap and open the Catalog window.
    2. Right-click the mosaic dataset > Remove > Remove Raster.
      The tool can also be accessed by opening the Remove Rasters From Mosaic Dataset tool (Toolbox > Data Management Tools > Raster > Mosaic Dataset).
    3. Click the SQL button next to the Query Definition field. This opens the Query Builder.
    4. In the Query Builder, enter the following expression: Category = 2 Click OK.
      If the overview creation is canceled or fails, use 'Category = 3' as the definition query to remove the failed overviews.
    5. Accept the default setting and run the tool.
