---

When you select a Job then it is possible that the users and groups tab will be enabled.

If that is the case then you can select users and groups for which the cron job will be executed.

The cron job will then be executed for every user/group that you have selected for it.

This option will not be available for every cron job.

Troubleshooting

If the cron module is installed and you have enabled some jobs for it and you found out that the jobs are not executed then you need to check if the server(system) cron deamon (Crontab) is calling the Group-Office cron controller every minute.

On ubuntu systems you can check that by going to the folder:

/etc/cron.d/

In that folder you should find the file:

groupoffice-cron

If the file does not exist then you need to create it and add the following code into it:

* * * * * www-data php /usr/share/groupoffice/groupofficecli.php -r=core/cron/run -c=/etc/groupoffice/config.php > /dev/null

On windows it should be something like:

c:\php\php-win.exe -c c:\path\to\php.ini -f c:\path\to\groupofficecli.php -- -c=c:\path\to\config.php -- -r=core/cron/run -- -q
