Migrated exchange 2007 to 2013. I know Public Folders are a mailbox now.

My question is why do some users with outlook 2010 see the Public Folders under "Tasks" on the left vertical bottom of outlook with "Folder List" highlighted and other DON'T -They just don't see anything under "Tasks" on the left vertical bottom of outlook with "Folder List" highlighted

Also (in a newly created email) if they go to the address book drop down click on Public Folders entry its empty.

any help would be appreciated

Make sure Outlook 2010 is at the latest service pack and patch level.

especially step 8.  Make sure that Set-OrganizationConfig is properly configured, and that the failing mailboxes don't have an invalid value for -DefaultPublicFolderMailbox.
