Exchange 2010 Public Folders not visible through OWA

During a Transition from Exchange 2003 to 2010, You may not be able to see the public folder hierachy and recive the following error:

the public folder you’re trying to access couldn’t be found. if the problem continues, contact your helpdesk and tell them the following the public folder couldn’t be found because there are no exchange 2010 public folder servers

In the Event log, you may recieve the following message:
Event ID 2161
"Event ID 2161" Validation - "publicfolderhierarchy". error message: you must provide a value for this property:

Fix
===
Find the offending Public folder through ADSIEDIT, find attribute msexchowningpftree
This will be empty or not set, simply find a working PF Folder and copy the attribute, or get the Distinguised name from the "folder hierachy" object and copy this into the missing attribute.

We saw this error on 2 offline public folder stores, which were using doubletake.

  1. Great fix easiest way to get the "folder hierachy" is to export list the folder" CN=Configuration,CN=Services,CN=Microsoft Exchange,CN=Organization,CN=Administrative Groups,CN=Administrative group, cn=Folder Hierarchies." Save it and then open it with notepad then copy the long distinguised name (The second line -third item in the list) & paste that into the attribute msexchowningpftree.
