Any - Exchange 2007,2010+ - Accessing mailboxes with ExFolders utility

Postby lmmtux » Wed Apr 02, 2014 10:30 am

The ExFolders utility for Exchange allows direct access to the entire Exchange mailbox, including all hidden folders that you cannot see with Outlook or Outlook Web Access. This can be useful for troubleshooting mailbox issues. ExFolders can also handle setting folder permissions as well.


  • Download the ExFolders utility from Microsoft for your specific version of Exchange. The latest version of ExFolders should be able to connect to Exchange 2010 and Exchange 2007, but not earlier.
  • To use ExFolders, you must extract it and run it directly on the Exchange server and place the "ExFolders.exe" in the Exchange "Bin" folder, commonly found here : c:\Exchange Server\V14\Bin\.
  • You may also need to use the registry settings file included in the ExFolders download called "TurnOffSNVerificationForExFolders.reg", if ExFolders.exe crashes. This adds a registry entry to allow it to run.
  • You will need Full Access Permissions to the mailbox you wish to connect to in ExFolders (In the Exchange console, right-click on the mailbox, and select "Full Access Permissions", and add the user account that will be running ExFolders to the list).

Using ExFolders

Run ExFolders on the Exchange mailbox server. It will open to a blank empty window. You must connect to the database by gong to the File menu, then "Connect". Select the Exchange database and ensure the Global Catalog server is correct for your domain.

Click OK to select the database to open. You should be provided with a list of mailboxes located in this database. Double click on the mailbox to open it.

You should see a list of all folders in the mailbox in the right pane, but you can also expand the folders in the left pane to see a hierarchical view.

The common mailbox folders that are visible from Outlook or Outlook Web Access will be located under the top level folder called "Top of Information Store".

For any folder, you can right-click on it, for additional options:

  • Folder permissions
  • Propagate folder ACEs
  • Property Editor
  • Bulk Property Editor
  • Show deleted subfolders
  • Clear permissions

To set permissions, select the group in the left pane and its respective permissions in the right pane. This is similar to the permissions tab in Outlook for folders. Groups that are visible in the Global Address List (GAL) will be available to add to this list. You can temporarily show hidden entries from the Global Address List to grant permissions then hide them after you are done. This is an advantage of ExFolders over Outlook since it does not use the Offline Address Book (OAB) so it sees a live address list rather than a cached one as Outlook does in "cache mode". Turning off "cache mode" in Outlook also provides a live view of the address list, too.
