Hi Team,

We Have created one .net core application which will read and process outlook inbox mails. It was deployed to windows scheduler.

So scheduler will run every three minutes and read inbox. On that note sometimes we are getting below issues. Please provide your suggestion.

Hi @Durga Kinthada (CON) ,Welcome to Microsoft Q&A,

Are there more details? Since it happens sometimes, have you considered putting the running code into a try catch to handle or skip the error?

            List<Attachment> attachments)
        {
            try
            {
                if (!IsOutlookInstalled())
                {
                    logger.Warn("Outlook is not installed");
                    throw new System.Exception("Outlook is not installed");
                }
                else
                {
                    OutlookApp outlookApp = new OutlookApp();
                    MailItem mailItem = outlookApp.CreateItem(OlItemType.olMailItem);
                    mailItem.To = email;
                    mailItem.Subject = subject;
                    mailItem.HTMLBody = body;
                    foreach (var attachment in attachments) mailItem.Attachments.Add(attachment.FilePath, DisplayName: attachment.Name);
                    mailItem.Display(false);
                }
            }

private static bool IsOutlookInstalled()         
{           
  Type officeType = Type.GetTypeFromProgID("Outlook.Application");
  if(officeType == null)
