• Select view as “All” and click on “I” character.
• Click on “Inbound_Polling_Scheduling_Time” and open it.

• In Local Translations / Overrides section click on “New Local Translations / Overrides” button.

• Select the Language.
• Put the integer time interval you want to receive incoming messages every n minutes.

• Click on Save
• Now, you will receive incoming messages every n minutes.

Note :

Decreasing Incoming message receiving interval will cause daily API Callout increase. So, please monitor the Governor limit of API Callouts in Company Information.
