Azure function timer trigger not properly executing on CRON expression

Question

I am using azure timer trigger function for triggering every 15 minutes in a day. So I set the time in TimerTrigger->Integrate->Schedule as 0 */15 * * * *. But the function is executing on every 5 minutes.

Is any problem in given CRON expression?

0 */15 * * * * is correct and I see function executes every 15m. Might be a silly suggestion but have you clicked Save after modifying the schedule? — Jerry Liu
Looks like the function is consuming the old code(template is 5m). Just in case, have you tried the steps like refreshing(button next to functionapp), restarting or deleting and recreating? — Jerry Liu
You mean after updating the Shedule time, then restart the function, right? — Jinesh
Yes. But function runtime is supposed to reload the file changes automatically without any manual steps. Not sure what goes wrong on your side. — Jerry Liu

Your expression is wrong.

Try these

0 */15 * ? * * // every 15 minutes starting at minute :00, of every hour

* 0/15 0 ? * *  //every 15 minutes starting at minute :00

You can test it in cron generator
