Ralph, we are currently trying to modify the email configuration within JTS and are having problems getting the username and password to be set to blank.  It will not save if you leave them both blank.  Therefore, we were trying to change them directly in the teamserver.properties file (not via the JTS configuration page), but have been unable to save the file.  We get a permissions denied error.  Our infrastructure team has verified that we have the correct permissions to that file, so was wondering if JTS locks that file thus denying us permission to change it.

I am just telling you the options. How you decide to do it is up to your team. The other answer is valid as well.

Thanks, Ralph.  I forgot that we had gone into the Advanced Properties and tried it there as well.  It won't let you save the SMTP Username and Password as blank; it requires you to enter a value (even though the IBM help documentation states that you can leave it blank).  That is why we were going to the Microsoft file level to try to change it there, but ran into the permissions error.  I submitted another question on Jazz.net to help us resolve this error with the SMTP Username and Password, but haven't received an answer.  We have also opened up a PMR since we have run out of options to try to fix our User Authorization error for a mail server which requires no authentication.

Thanks for the feedback. As long as it solves your issue, all is fine.
