## 23.1 Resource scheduling principle

Creation of a new resource in Kerio MailServer creates a new account which includes calendar of the resource. This calendar will reflect all reservations.

Upon creating the first resource, a new contact folder called Resources is created. This folder will include individual resources. An email address is generated for each resource, consisting of its name and the domain (e.g. `meetingroom1@company.com`). The Resources public folder is used especially to avoid that users would have to remember names of the resources. Thanks to this feature, users simply select resources from the list.

Resource scheduling is based on a working Free/Busy calendar in the user's email client. Thanks to Free/Busy, it is clear at the moment of creation of an event whether the resource is available for the scheduled time or has been booked already. If users miss a working Free/Busy calendar, they can subscribe shared or delegated folders to access resource calendars. Users with rights for reservation of a particular resource can subscribe the calendar with read-only rights so that they can see in their mailboxes when the resource is free or booked.

### Reservation manager

As described above, the resource scheduling is outlined so that resources are managed separately in the system. Moreover, there is a user with special rights called resource manager in the system who can access resource calendars and change their events, move them, remove them or create new ones. The main role of the resource manager is to solve possible collisions and decide on priorities.

### Setting a resource temporarily unavailable

Resources can be also temporarily disabled in the system without the need to remove it for good. This option is helpful especially when a resource is temporarily unavailable for any reason (e.g. a car in servicing). Disabling of a resource results in the following consequences:

- users will not see the resource in the Resources public folder,

- the calendar of the resource will not be available for subscription or delegation,

- calendars already subscribed will be disconnected from user mailboxes automatically,

- in the Free/Busy calendar, the resource is showed as long-term busy,

- if a user reserves a disabled resource anyway, a DNS message will inform them that the reservation cannot be delivered.

### Resource details

By default, resource calendars do not show possible notes and message subject. If you wish that resource calendars showed such information, follow these instructions:

1. Stop Kerio MailServer.

2. Go to the directory where Kerio MailServer is installed (`Kerio\MailServer`) and open the `mailserver.cfg` file.

3. In the configuration file, find the resource for which you wish the details to be shown.

4. Set the `ClearEventSubject` variable to `0` and save changes.

5. Run Kerio MailServer.
