Interesting problem with ews managed api 2.0

just started on a blank visual studio installation writing a new ews application.

Everything went fine, i tested it with an testmail ive sended from my new application an everything works great.

Next step should have been to retrieve two test-mails from my inbox via the "findItems" method, but when i'm trying this, i get always a timeout.

i dont understand it, because sending e-mails works but retrieving gives a timeout. does anybody can help out here?

thank you

this is the code i use right now:

    {
        static void Main(string[] args)
        {
            
            ExchangeService service = new ExchangeService();
            service.Credentials = new WebCredentials("user", "password");
            service.Url = new Uri("https://web.mydomain.com/EWS/Exchange.asmx");

            if (service != null)
            {

                ItemView view = new ItemView(10);
                view.PropertySet = new PropertySet(BasePropertySet.IdOnly, ItemSchema.Subject);
                SearchFilter searchFilter = new SearchFilter.ContainsSubstring(ItemSchema.Subject, "test");
                
                FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, searchFilter, view);

                Console.WriteLine(findResults.TotalCount);
            }

        }

    }```

Thanks Glen, for your answer!

I wonder about the timeout because there are only 2 mails inside the inbox of the targeteted mailbox.

I tried your changes, but get the same error. I think it must be something with the communication with the server in general. maybe another port for incoming mails is used that the port i use, when i want to send an email?

this is, what the trace said:

`

With a Search like your using on a Mailbox folder that has a very large item count a timeout wouldn't be unexpected. I would suggest you include a Time Restriction at least in your filter eg

        SearchFilter searchFilter = new SearchFilter.ContainsSubstring(ItemSchema.Subject, "test");
        SearchFilter DateRestrication = new SearchFilter.IsGreaterThan(ItemSchema.DateTimeReceived, DateTime.Now.AddDays(-7));
        SearchFilter sfCol = new SearchFilter.SearchFilterCollection(LogicalOperator.And) { searchFilter, DateRestrication };

        FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, sfCol, view);

or better using AQS/KQL

       FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, "Subject:test", view);
