Java – regular expression – replaces characters (commas) between double quotes if patterns match

I have this log from the exchange server

I use this regular expression to match and group patterns;

Basically, the information in the log is separated by commas Unfortunately, for the "email subject" field, if the user enters a comma, the log will be displayed in double quotation marks, such as the example above - a comma with a date format of "Monday, May 24, 2010"

How to grab commas together with commas without double quotes in a specific group (Group 19)
