c# - Get the target MAPI Folder and EntryID of a MailItem after applying Outlook rules -

i'm creating add-in outlook 2007, handles newmailex event , gives storeid of mapi folder , entryid of incoming email in folder, after outlook rules applied it. add-in track email later, using getitemfromid() method of system.namespace class. tried searching unique pr_search_key of mailitem, taking time unnecessarily scanning folders , sub-folders. need way remember email, , not searching again.

when handling newmailex entryidcollection containing comma separated string. these guids. need save string somewhere (or id wish save) , can item(s) using

outlook.mailitem mi = thisaddin.application.session.getitemfromid(id, type.missing) outlook.mailitem 

where id single id item want. you'll have call once each item in collection. doesn't matter ends after rules applied. id same.

@rotard contact folder use

public string getfolderfullname(outlook.contactitem ci)  {      outlook.mapifolder mf = ci.parent;      string path = mf.folderpath;      return path;  }
