The issue described is that the flow "does not properly extract birth dates." This points to a problem with data manipulation or logic within the flow, not connectivity. In Power Automate (formerly Microsoft Flow), expressions are used to perform operations on data, such as formatting dates, converting data types, or extracting specific parts of a text string. An incorrect expression is the most likely reason the birth date is not being processed correctly for the comparison or for use in the email greeting.

A. Connectors: A connector is responsible for establishing the connection to the data source (e.g., SharePoint, Dataverse). A connector issue would likely result in a failure to retrieve any data, not an incorrect extraction of it.

C. Templates: Templates are pre-built flows that serve as a starting point. The flow has already been created and is running, so modifying a template would not fix the logic within this specific, existing flow.

such as dates

within a flow's logic. It states

"In any flow

you use expressions to work with data."

2. Microsoft Learn. "Reference guide for workflow expression functions in Azure Logic Apps and Power Automate." Power Automate Documentation. This guide provides a comprehensive list of functions available in expressions

including date and time functions like formatDateTime() and addToTime()

which are essential for handling date-based logic like a birthday check.

3. Microsoft Learn. "Connectors overview." Power Automate Documentation. This source defines connectors as proxies or wrappers around an API that allow the underlying service to talk to Power Automate. Their role is connectivity

not data processing logic within the flow itself.
