Hi allanwei,

Thanks for feedback.

This error occurs due to too many calls are going out from your flow to Office 365 Users connector and you are hitting the limit on it.

If possible, please provide your Flow Id. I will help confirm this issue on my side.

Best regards,
Mabel Mao

Hello, how can I know what is the "available hits" threshold?

I am not asking about what can be found in documentation, but getting a number in run time. Something like a query which gives a number or percentage of currently used API calls or something relevant.

Simply speaking - how can measure usage of resources?

best regards

Andrzej
