Problem after deleting legacy exchange administrative group

To start with you generally do not want to delete it but if you already did…..Start ADSI Edit. In the CN=Configuration container, locate the following container:

CN=Services,CN=Microsoft Exchange,CN=ORGANIZATION,CN=Administrative Groups,CN=administrative_group,

Now we were missing the ‘Folder Hierarchies’ folder – All we have to do is recreate it as follows:
Create the “Folder Hierarchies” under the Exchange Administrative Group

1. Right click on Exchange Administrative Group
2. Select New Object
3. Select msExchPublicFolderTreeContainer for the class and click Next
4. Enter the following for the value: Folder Hierarchies, click Next
5. Click Finish

Create Public Folder Tree Object

1. Right click CN=Folder Hierarchies -> New Object
2. Selected msExchPFTree for the class
3. For the value we entered, “Public Folders” and clicked next
4. Clicked on the “More Attributes” button, selected msExchPFTreeType and set the
value to 1. Note: This is very important that this value is set to a value of 1 as
this tells Exchange that this is a MAPI Tree
5. Click Ok and then finish

Populate msExchOwningPFTreeBL attribute object of the PF Stores in the organization
(Since this attribute is not directly editable, you have to follow the below steps
to do this for each PF store)

1. Get properties of the newly created “Public Folders” Tree object in ADSIEdit.
2. Copy the distinguishedname value to the clipboard and then click cancel.
3. Navigate to the Storage group that contains the Public Folder Store for this
server and get properties of the server database.
4. Locate the msExchOwningPFTree attribute and paste in the value that was copied
to the clipboard in step 2. Click OK.
5. Restart the Information Store Service

Set permissions on the Public Folders

1. Start ADSI Edit. In the CN=Configuration container, locate the following container:
   • CN=Services,CN=Microsoft Exchange,CN=ORGANIZATION,CN=Administrative Groups,CN=administrative_group,CN=Folder Hierarchies,CN=Public Folders
   • Note In this container, ORGANIZATION is the name of the Exchange Server organization and administrative_group is the name of your administrative group.
2. Right-click CN=Public Folders, and then click Properties.
3. Click the Security tab.
4. Make sure that the Allow inheritable permissions from parent to propagate to this object check box is selected.
5. Make sure that the Everyone group has the following Allow permissions:
   • Create named properties in the information store
   • Create public folder
   • Create top level public folder
   • If the Allow inheritable permissions from parent to propagate to this object check box is selected, the Everyone group should already have these permissions. Make sure that the Deny check boxes are not selected.
6. Now try to mount the PF store and see if we can access it fine now.
