Cannot edit public folder items that were migrated from Exchange 2003 to 2007

I recently migrated an SBS 2003 server to SBS 2007.  The public folder items that were migrated from the 2003 server cannot be edited.  Users can create *new* items.  I ran a Exchange 2007 command to grant a test user administrative permissions; however, thet test user still cannot edit previously created public folder items.

maybe the permissions take their time.
we had a similar problem with permissions.
it took 1 night to get them working.

or try a restart....

what command did you run?
mtallonAuthor Commented:
I ran the Add-PublicFolderAdministrativePermission command on the test user.  I did it a few weeks ago.  I cannot recall if I have restarted since then.  I will restart the server and see if that helps.

What command did you run to set the permissions?
mtallonAuthor Commented:
I restarted the server and it did not resolve the problem.  Domain users still cannot edit Public Folder calendar and contact items that were created on the old server.

Can you not just export all public folders to a PST File or to several PSTs according to different departmental Public Folders

Then delete the public folders you have

Create a new database for Public  Folders and then import them in ?

This way you should be able to apply / assign permissions / roles to your users

Also Administrative Permissions are different, have a look at the following article :

PF permissions can be assigned via MS Outlook 2007 as well, as long as the mailbox owner have appropriate rights
