Get Outlook Out of Office status using C#

[fayazmd]

I am working in a web application where i am sending mails to employees. I have to send mails to persons whose outlook out of office is set to false. And I need to know one's out of office status. For that I used the following code. By using this I am getting my outlook out of office status. But how can I get other employees Out of office staus? My code is

 OutLook.NameSpace oNS;
        OutLook.Stores oStores;
        //OutLook.Store oStr;
        OutLook.PropertyAccessor oPrp;

        OutLook._Application outlookObj = new OutLook.Application();
        
        oNS = outlookObj.GetNamespace("MAPI");
        oStores = oNS.Stores;
        

        foreach(OutLook.Store oStr in oStores)
        {
            if(oStr.ExchangeStoreType == Microsoft.Office.Interop.Outlook.OlExchangeStoreType.olPrimaryExchangeMailbox)
            {
                oPrp = oStr.PropertyAccessor;
                bool OutOfOffice = (bool) oPrp.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x661D000B");                                
            }
        }

Unless you are able to provide their credentials to login, I am not sure you can do that.

Why not send emails to all of them have something in place to intercept the "out of office" auto-reply and ignore it?

Hi Plater,

We have microsoft office communicator. If any body, sets out of office, it gets reflected in communicator. How this is possible, if credentilas are required to know the status.

Unless you are able to provide their credentials to login, I am not sure you can do that.

Well there is bound to be a like "administra tor" credential into the communicator system that can view all the statuses.
I am unfamiliar with communicator and that whole setup thought.
