Exchange 2010 Public Folder Missing

There seems to be an issue with Exchange 2007 / 2010 where the public folders disappear. The database files reside on the drive but they do not appear in the Exchange Management Console and noone can access them in Outlook. To resolve the issue carry out the steps below :-

Open ADSI Edit (adsiedit.msc). Right click on Adsiedit at the top and click connect to..

AdsiEdit1

Change the context to Configuration and then click ok.

AdsiEdit2

Branch out to the following location :

Configuration, Services, Microsoft Exchange, Exchange Organisation Name, Administrative Groups, Exchange Administrative Group, Databases.

You should see a folder called CN=Folder Hierarchies

PublicFolders1

If you dont see the folder CN=Folder Hierarchies. Right click on the Exchange Administrative Group folder and select New Object.

PublicFolders3

Select msExchPublicFolderTreeContainer as class and click Next

PublicFolders4

Enter the following as value: Folder Hierarchies, click Next, Finish

PublicFolders5

Right click on the new Folder Hierarchies folder and select New Object

PublicFolders6

Select msExchPFTree as class, click Next

PublicFolders7

Enter the following as value: Public Folders, click Next

PublicFolders8

Click on More Attributes button.

PublicFolders9

select msExchPFTreeType and set the value to 1

PublicFolders10

Click OK then click Finish

Double click the newly created “Public Folders” folder.

Double click distinguishedName.

PublicFolders11

Highlight the value of this box. Copy the value to the clipboard then click Cancel.

PublicFolders12

Now we need to put this value in the right place. Branch out the following in adsiedit.

Exchange 2007

Configuration, Services, Microsoft Exchange, Exchange Organisation Name, Administrative Groups, Exchange 2007 Administrative Group, Servers, Affected Exchange Server, Information Store, Storage Group, Public Folder Database

Exchange 2010

Configuration, Services, Microsoft Exchange, Exchange Organisation Name, Administrative Groups, Exchange 2010 Administrative Group, Databases, Public Folder Database

Right click on the Public Folders folder on the left. Click on Properties.

PublicFolders13

Scroll down and edit the msExchOwningPFTree attribute.

PublicFolders14

Paste the value that was copied to the clipboard earlier.

PublicFolders15

Click OK twice

Now restart the information store service. Once started you should hopefully see the public folders in the exchange management console. Also restart the Microsoft Exchange System Attendant Service
