Azure函数在visual studio中工作正常，但一旦发布就不会触发

Question

我创建了一个azure函数，该函数连接到exchange服务器，并由blob存储触发器触发。在visual studio中测试这一点，一切都很好；上传blob将触发该函数，并尝试连接。

然而，当我将该函数发布到Azure时，它不再由上传文件时的blob存储触发。

应用程序和函数在azure portal上都是可见的，并且应用程序正在运行。但是调用日志声明该函数从未被调用。由于该函数是在Visual Studio中开发的，因此也将其列为只读函数。

using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Exchange.WebServices.Data;
using System;
using Microsoft.WindowsAzure.Storage.Blob;
using System.Security;
using System.Net;

namespace ExchangeSimplifiedTestFunction
{
    public static class SimplifiedFunction
    {
        [FunctionName("SimplifiedFunction")]
        public static void Run([BlobTrigger("exchangestorage/{name}", Connection = "StorageConnection")]CloudBlockBlob myBlob, string name, TraceWriter log)
        {

            log.Info($"C# Blob trigger function Processed blob\n Name:{name} \n Size:  Bytes");
            log.Info(myBlob.ToString());
            ExchangeService service = new ExchangeService();
            String customer = myBlob.DownloadText();


            string emailAddress = "[e-mail]";

            //yuck yuck yuck yuck yuck 
            var password = new SecureString(); foreach (char c in "password") password.AppendChar(c);

            NetworkCredential userCredentials = new NetworkCredential(emailAddress, password);
            service.Credentials = userCredentials;

            bool success;
            try
            {
                service.AutodiscoverUrl(emailAddress, RedirectionUrlValidationCallback);
                success = true;
            }
            catch (Microsoft.Exchange.WebServices.Data.AutodiscoverLocalException e)
            {
                log.Info($"loginFailed - expected during testing");
                success = false;
            }

            if (success) { log.Info($"Successfully connected to exchange server"); }

        }

        private static bool RedirectionUrlValidationCallback(string redirectionUrl)
        {
            bool result = false;
            Uri redirectionUri = new Uri(redirectionUrl);

            if (redirectionUri.Scheme == "https")
            {
                result = true;
            }
            return result;
        }

    }
}
