I cannot work out how I can do what I need to do.
I have a method called 'MarkAsRead' that takes an ItemID and should mark the mail item as read.
But it seems that the Item doesn't have an 'IsRead' proeprty, only an email does, so I need to cast my Exchange WebServices mail item to an email message.
here is the code:
try
{
System.Diagnostics.Debugger.Break();
//creates an object that will represent the desired mailbox
Mailbox mb = new Mailbox(common.strInboxURL);
//creates a folder object that will point to inbox fold
FolderId fid = new FolderId(WellKnownFolderName.Inbox, mb);
//this will bind the mailbox you're looking for using your service instance
Microsoft.Exchange.WebServices.Data.Folder inbox = Microsoft.Exchange.WebServices.Data.Folder.Bind(service, fid);
//// if the property is not loaded yet, first load it
//mail.Load(PropertySet(BasePropertySet.IdOnly, EmailMessageSchema.IsRead));
//if (!mail.IsRead) // check that you don't update and create unneeded traffic
//{
// mail.IsRead = true; // mark as read
// mail.Update(ConflictResolutionMode.AutoResolve); // persist changes
//}
// As a best practice, limit the properties returned to only those that are required.
PropertySet propSet = new PropertySet(BasePropertySet.IdOnly, ItemSchema.Subject);
// Bind to the existing item by using the ItemId.
// This method call results in a GetItem call to EWS.
Item item = Item.Bind(service, itemId, propSet);
EmailMessage mail = Item.Bind(service, itemId, propSet);
item.Load(new PropertySet(BasePropertySet.IdOnly,EmailMessageSchema.IsRead));
item.IsRead = true;
item.Update(ConflictResolutionMode.AlwaysOverwrite);
return true;
}
I am trying to do something like this:
// if the property is not loaded yet, first load it
mail.Load(PropertySet(BasePropertySet.IdOnly, EmailMessageSchema.IsRead));
if (!mail.IsRead) // check that you don't update and create unneeded traffic
{
mail.IsRead = true; // mark as read
mail.Update(ConflictResolutionMode.AutoResolve); // persist changes
}
unfortunately I need to be able to get a unique email message from the item.
how can I do that please?
