Replace text string using batch file

Previously I recieved help from SteveGTR to create the batch file below which changes the UserName variable into a different format then calls on a standard PRF file and creates a new one with the correct UserName format.  The problem was that the batch file replaced the Value for MailboxName in each section and not just in section 4 where it was needed.  So the only way I can think to correct this issue is to make the MailboxName in section 4 unique and for the batch file to look for that instead.

So I changed the PRF (in section 4) and the batch file from MailboxName to MailboxNameChange and it has the desired effect.  Problem is that I now need the same batch file to look for anything in the output file by the name of MailboxNameChange and convert it back to MailboxName so that I can run the PRF correctly.

Thanks
