I'm trying to develop an addin for OutLook 2007 using Visual Studio 2008 Visual Basic. In my outlook 2007 I have 2 accounts: my.name@pop3.mail this is using the OUTLOOK.PST file my.name@imap.mail using : OUTLOOK.xxx.yyy.0000001.PST file I'm trying this simple code : ColStores = Me.Application.Session.Stores Debug.Print("+---- start ----------------------------------------") Debug.Print("| stores count =" + ColStores.Count.ToString) Debug.Print("+---------------------------------------------------") For i = 1 To ColStores.Count FilePathName = ColStores(i).GetRootFolder.Store.FilePath Debug.Print("| i =" + i.ToString + " " + FilePathName) Next Debug.Print("+---- end -------------------------------------------") this is the output +---- start ---------------------------------------- | stores count =2 +--------------------------------------------------- | i =1 C:\Documents and Settings\...\Microsoft\Outlook\Outlook.pst | i =2 +---- end ------------------------------------------- FilePathName for i = 2 is set to <nothing> the stores count : 2 is correct but why there is not the path and file name of the PST file used by the IMAP account ? Thanks a lot Alberto
