I tried this on Arcmap 10.4:
- Locate the following tool -
- ArcToolbox > Conversion Tools > To Shapefile > Feature Class To Shapefile (multiple)
- Launch the tool and add your Polygon ZM shapefiles to the input features.
- Select an 'Output Folder'
- Click on the 'Environments...' button at the bottom of the dialog box. To the right of the 'OK' button.
- Click on the 'General Settings' text.
- You should see two fields marked 'Output has Z Values' and 'Output has M Values'.
- Set both fields to 'Disabled'.
- Click 'OK' to exit the Environments Settings then click 'OK' to run the tools.
