I am trying to open the root folder on Exchange 2007 using MAPI. If I use the following... HrMAPIOpenFolderEx(lpMailbox, '\\', szStoreFolderPath, &lpRootFolder) I can open the @PR_IPM_INBOX_ENTRYID but when I try and open @PR_IPM_SUBTREE_ENTRYID it fails. This works with Exchange 5.5 thru 2003. Did they change the name of the root folder? How do I access the root folder for Exchange 2007 (on a client with MAPI support). If I look at it in OutlookSpy it still says IPM_SUBTREE for the display name property on the root folder. Thanks, David

You have a couple of choices: 1. get the EDK source and trace through it to work out what's going on 2. just write code yourself to read PR_IPM_SUBTREE_ENTRYID and openentry on that (or use the source code from MFCMAPI as a newer place to get sample code from -- that navigates down to top-of-info-store by opening the entryid above. If MFCMAPI doesn't work, then something strange is going on). -- dan
Dan, Thanks for the suggestion. I started to play with the EDK source and for the heck of it used the string "Top of Information Store" instead of the @PR_IPM_SUBTREE_ENTRYID and it worked. Not sure if it will cause me grief in other languages.
