Items that you post in public folders that are configured as newsgroup folders or Network News Transfer Protocol (NNTP) folders may be converted to the IPM.POST message class, no matter what the original class of the item was. This conversion may break the functionality of non-NNTP items (for example, an item with an IPM.TASK message class).
When the NNTP service is running, the service is notified when new items are added to folders that are published as newsgroups. This problem can occur because the message class of these items is then changed to IPM.POST, regardless the original class. The NNTP service does not check to make sure that it is forcing only items that do not have an original class to the IPM.POST message class.
