Exchange server doesn't support the requested version

I get this error because the FindItemsResult isn't compatible with exchange version I'm using which is 2013.

Exchange Server doesn't support the requested version.

My codes:

C#

SearchFilter sf = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));
        FindItemsResults<Item> items = service.FindItems(WellKnownFolderName.Inbox, sf, new ItemView(10));

        foreach (Item item in items.Items)
        {
            PropertySet propSet = new PropertySet(BasePropertySet.IdOnly, ItemSchema.TextBody);
            EmailMessage email = EmailMessage.Bind(service, item.Id, propSet);
            Program.SearchItems(email);  
        }

What I have tried:

I could just change it into Exchange 2010 but I get an error in TextBody since this is only for Exchange 2013 and later versions.

Is there any way to convert the code which can work in Exchange 2013?

What does the code look like where you created your service, ExchangeService, object?

Judging by the error message, it would seem that the server either isn't running Exchange 2013 or the code you used to create the ExchangeService object isn't using the Exchange version you assume it is.

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);

OK, next step is to look at the contents of service.ServerInfo and verify that is contains what you expect.

It's in version 14.3.210.4002 so I should be using Exchange2010_SP2. I did first but I can't use the ItemSchema.TextBody because it isn't compatible in 2010 version so I changed it but got the error in FindItemsResults instead.

I've already solved this.
