In response to your first question, yes it occurs for a user I am the user.

Many thanks in advance for any help with this problem. I am using Outlook in Office 2010 and the hosted exchange service is using Exchange 2013. Why is this happening, and how can I delete these folders without triggering these notices? I worry that these notices are also going out to those with whom those old messages were originally exchanged. This appears to happen with each of the messages in the folder that was subject to tracking at the time it was sent, but in fact The problem is this: When I attempt to delete one of these duplicate folders, it automatically generates a number of email notifications - from myself to myself - reporting that a message has been deleted This process has resulted in a number of duplicate folders which I have attempted (The business domain is a MAPI account the personal domain is an IMAP account.) In doing this reorganization, I have copied a number of folders in which I store old email from the business account (MAPI) to the personal account (IMAP). I have recently moved into a hosted exchange situation for my business domain and established a new personal domain there as well.
