Get file Hash (MD5/SHA256) via EWS API without copying the physical files out of Exchange RRS feed

  • Question

  • We are looking for a way to get attachment's file hash from Exchange without having to copy the physical files themselves out of Exchange in order to do this. We have access via EWS API to both Exchange On premise and Exchange Online (O365). I have heard it is possible though could not find any documentation.

    Our application uses EWS API and need to scan the mail-store for example: all emails in marketing group that have doc files attached and return the file hashes.

    Any solution how to get file hash from Exchange?
