What's the cause for “PR_INTERNET_REFERENCES is too large and requires streaming” when using EWS Managed API?

问题

An application uses EWS Managed API to fetch and process large quantities of Exchange items. The items are loaded using ExchangeService.LoadPropertiesForItems(items, propertySet).

During the items' processing, when a property of an item is being accessed, the following exception is thrown:

Microsoft.Exchange.WebServices.Data.ServiceResponseException: Data is corrupt., The object data is corrupted. The value of property [0x1039001f] PR_INTERNET_REFERENCES is too large and requires streaming.

The only thing I could find so far is an advice to use BindToItems() instead of LoadPropertiesForItems(), but I didn't try it out yet (I cannot reproduce the issue consistently).

My question, then, is: How do I do the streaming mentioned in the error (if that is what I need to do at all)?

Update (added some code examples)

var basicPropertySet = new PropertySet(BasePropertySet.IdOnly, ItemSchema.LastModifiedTime, ItemSchema.ParentFolderId)
{
    new ExtendedPropertyDefinition(0x300B, MapiPropertyType.Binary)
};

var detailsPropset = new PropertySet(ItemSchema.Id, ItemSchema.LastModifiedTime, ItemSchema.DateTimeReceived,
    ItemSchema.ParentFolderId, EmailMessageSchema.IsRead, ItemSchema.Subject, EmailMessageSchema.From)
    {
        new ExtendedPropertyDefinition(0x300B, MapiPropertyType.Binary), ItemSchema.MimeContent
    };

var filter = new SearchFilter.SearchFilterCollection
    {
        new SearchFilter.IsGreaterThanOrEqualTo(ItemSchema.LastModifiedTime, modifiedSince),
        new SearchFilter.IsLessThanOrEqualTo(ItemSchema.LastModifiedTime, modifiedBefore),
        new SearchFilter.IsEqualTo(ItemSchema.ItemClass, itemClass),
    };

var view = new ItemView(pageSize, 0, OffsetBasePoint.Beginning)
    {
        PropertySet = basicPropertySet
    };

    view.OrderBy.Add(ItemSchema.LastModifiedTime, SortDirection.Ascending);
// view.Offset is getting updated during the process

var items = exchangeService.FindItems(folderToScan.Id, searchFilter, view);

var ids = items.Select(item => item.Id).ToList();

exchangeService.LoadPropertiesForItems(items, detailedPropertySet);

foreach (var item in items)
{
    // verify properties are loaded, by simply accessing them
    // this is where the exception is thrown.
    itemx.From;
    item.LastModifiedTime;
    item.Id;
    item.MimeContent;
    item.Subject;
}
