Exchange Client Performance Analyzer (ECPA)
ECPA is a PII free and an extensible tool to collect network diagnostics from end user machine to O365 data centers. The tool is to be run from customer location to better understand the cause of latencies (if any) and to collect and upload all the diagnostic data to Microsoft (Client GUID is provided for reference). ECPA does not collect any Personally Identifiable Information (PII) data but it does need to know the physical datacenter location of the user’s mailbox, which is running the test. Once the right location is identified, the tool runs a series of performance related tests. Any valid O365 credentials can be used to login.
