In a users inbox I can see listed (with omcontain) messages with subjects like:
IPM.Configuration.RssRule
IPM.Configuration.ConversationPrefs
IPM.Configuration.TCPrefs
IPM.Configuration.Autocomplete
IPM.Microsoft.MigrationStatus
Outlok Message manager () (KEY:4756E )
Can these messages be deleted?
Any idea where they may have come from apart from some interaction with Outlook I'm sure?
