When you have the subscribers you want selected and the changes you want applied to those subscribers, press the “Update Subscribers” button here and those changes will be applied.  The progress bar will indicate how far along the process is and when it’s complete a dialog will pop up indicating we’re done and how many errors were encountered in the process.

 

You’ll be given the opportunity to view the output log automatically when the process is complete.  If there are any errors noted I strongly recommend you do so and search the log for “(error)” to find the problem.  Remember, a new output log is generated in the \logs folder under the BulkEdit installation directory each time you run the tool.
