Exchange Web Services client library v1.12.1 Release Notes

    • Lower the session pool size automatically in response to ErrorServerBusy and ErrorTooManyObjectsOpened errors from the server.
    • Unusual slicing and indexing (e.g. inbox.all()[9000] and inbox.all()[9000:9001]) is now efficient.
    • Downloading large attachments is now more memory-efficient. We can now stream the file content without ever storing the full file content in memory, using the new Attachment.fp context manager.
