If Microsoft Exchange database option is selected, the settings data will be stored under the Team Helpdesk Settings public folder in Exchange. This option removes the dependency of an external database and works even on WAN and HTTP connection to Exchange. This database option is best used for quickly evaluating Team Helpdesk in your environment without needing to configure a dedicated database. However, please be careful to not use this database option for your live production helpdesk, as it is unsuitable for multi-users helpdesk environment.
Notice the items under Team Helpdesk > Settings folder where the settings are stored.
