How far back in time does the SyncFolderItems store items? Is there a fixed number of days worth of items that can be synced using the SyncFolderItems operation or is it all the items from the beginning of time?
e.g: I have a mailbox that is 1 year old. If I run a SyncFolderItems operation today, without passing a SyncState cookie, will it sync all the items from the past year? Is there a way I can time-bound the sync(last 10 days' items), without having a SyncState cookie?
