Required arguments

connection_id
Syntax: string
Description: The ID of your Microsoft 365 connection.
Example in Canvas View: my-microsoft-365-connection

Optional arguments

initial_position
Syntax: LATEST | TRIM_HORIZON
Description: The position in the data stream where you want to start reading data. Defaults to LATEST.
  • LATEST: Start reading data from the latest position on the data stream.
  • TRIM_HORIZON: Start reading data from the very beginning of the data stream.
Example in Canvas View: LATEST

SPL2 example

When working in the SPL View, you can write the function using arguments in this exact order:

| from read_from_microsoft_365("my-connection-id", "TRIM_HORIZON") |... ;

Alternatively, you can use named arguments to declare arguments in any order. The following SPL2 example uses named arguments to specify the initial_position argument before the connection_id argument:

| from read_from_microsoft_365(initial_position: "TRIM_HORIZON", connection_id: "my-connection-id") |... ;

If you want to use a mix of unnamed and named arguments in your functions, you must list all unnamed arguments in the correct order before providing the named arguments.

Limitations of the Microsoft 365 source function

The Microsoft 365 source function uses scheduled data collection jobs to ingest data. See Limitations of scheduled data collection jobs for information about limitations that apply to all scheduled data collection jobs.
