Thanks Tobias, This seems to be working. Keith Hi Keith, looking at <install-root>\OTRS_Restart.bat you find the command: perl.exe <install-root>otrs\bin\Cron4Win32.pl This re-reads "var\cron\postmaster_pop3.dist" and updates "CRONw\crontab.txt". There you will find the updated value. Restart of OTRS should not be necessary as the crontab.txt may be updated while the cron service is running and it picks up any changes. At least CRONw\README.txt says: <quote> The service will parse the crontab again if it the file modification time changed since last parsing so feel free to alter the crontab while the service is running. </quote> What I don't know is, how often the cron service checks the crontab.txt for modifications. You may force by restarting cron only (without OTRS as a whole) using the commands "net stop cron" and "net start cron". So what you will have to do is: * Update var\cron\postmaster_pop3.dist * Call perl otrs\bin\Cron4Win32.pl * (optional) "net [stop|start] cron" That should do it. HTH, Tobias
