During an in-house reproducing, the error message, "ERROR 999999" is returned if the worksheet, saved in the C drive, is added to a map. The tool runs successfully when the worksheet is not on the map, even if no edits are made. 

For the user, the error message, "ERROR 999999," occurs when the worksheet from the network drive is added, but not when the file is moved to a C drive.
