This might be stupid but i have been looking for this for a long time now and i still don't have any idea on how to do it. my problem is that i got a folderId(which has no name but just the UniqueId) coming from an event and i want to know if this forder is the DeletedItems one.
when i call the methods :
new FolderId(WellKnownFolderName.DeletedItems)
or
new FolderId(WellKnownFolderName.DeletedItems, mailBox)
i just get a FolderId which name is set but UniqueId is still null, therefore i can't compare UniqueId, the method Equals also fail... Btw, i working on exchange server 2013 with an impersonatedUser.
Edit : I feel even more stupid as i finally found out how easy it was : *
var folder = Folder.Bind(ewsInstance, WellKnownFolderName.DeletedItems);
if (Equals(event.ParentFolderId.UniqueId, folder.Id.UniqueId))
Finaly found the answer :
var folder = Folder.Bind(ewsInstance, WellKnownFolderName.DeletedItems);
if (Equals(event.ParentFolderId.UniqueId, folder.Id.UniqueId))//...
