How to Validate a MSG Email File in Python

Corrupt or improperly formatted MSG files make the information they hold inaccessible, so it’s critical that we validate these files before they reach their end destination. Thankfully, the below API solution will make that process a breeze. With only a few lines of Python code provided below, you can quickly & easily call our “Validate MSG File” API, which will determine if MSG files are valid or invalid (and if the latter is true, it will provide detailed error/warning information to go along with it).

We can start our API call by running the below command to install the Python SDK:

pip install cloudmersive-convert-api-client

With that step out of the way, we can call the function (adding imports first):

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint

# Configure API key authorization: Apikey
configuration = cloudmersive_convert_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'



# create an instance of the API class
api_instance = cloudmersive_convert_api_client.ValidateDocumentApi(cloudmersive_convert_api_client.ApiClient(configuration))
input_file = '/path/to/inputfile' # file | Input file to perform the operation on.

try:
    # Validate if an MSG file is executable
    api_response = api_instance.validate_document_msg_validation(input_file)
    pprint(api_response)
except ApiException as e:
    print("Exception when calling ValidateDocumentApi->validate_document_msg_validation: %s\n" % e)

Now you just need to provide a Cloudmersive API key to complete your call, and you’re all done. You can get a free-tier API key by registering a free account on our website.
