After a tipoff from KC Lemson after I emailed my likes and dislikes to their exchange team (as she requested), I’ve installed the latest hotfix rollup for Exchange which includes a fix to the problem where Mail to a Public Folder Is Set as IPM.Post Instead of IPM.Note. We subscribe to mailing lists and use public folders as incoming “mailboxes” (like a distribution list but only one destination to prevent more than one person trying to action an incoming email. Instead they move the email into an actioned folder once they have actioned the email. Anyway – once the hotfix has been applied you need to edit the registry as per KB 817809 and bounce the information store. As we’re having a power cut at 12.30 today, the bounce will occur then and I’ll be able to test these changes.
