Some new users are unable to see public folders - Server: Exchange 2013 - Client: Outlook 2013

SYMPTOM:

Outlook Public Folder Not Showing for some recently created users even after appropriate permissions were set via ECP

I would like to share the engagement which we had with Premier Microsoft Support to resolve the reported issue.

ENVIRONMENT: Exchange 2013 and Outlook Client 2013

CAUSE:

New users were assigned to wrong “DefaultPublicFolderMailbox”

RESOLUTION:

Executed the following command to change DefaultPublicFolderMailbox to the working Public Folder Mailbox for affected users.

            Set-Mailbox -Identity testpf1@qfcra.com -DefaultPublicFolderMailbox "qdfcra.com\users\All Public Folders"

To check to the default public folder mailbox of the user who can view public folder, output to a file:

Get-Mailbox -Identity usermailboxname (or usermailbox fqdn) | fl > publicfolder_visible.txt

To check to the default public folder mailbox of the user who cannot view public folder, output to a file:

Get-Mailbox -Identity usermailboxname (or usermailbox fqdn) | fl > publicfolder_notvisible.txt

ex: Get-Mailbox -Identity myname@myname.com | fl > c:\publicfolder_visible.txt

Open myname.txt and search for public folder and check the DefaultPublicFolderMailbox and compare to the mailbox users who already can view/ or has a functional public folder

Now set the user's DefaultPublicFolderMailbox whose public folder isn't visible to the user's DefaultPublicFolderMailbox identified from above process whose public folder is visible

Set-Mailbox -Identity TestPF1qfcra.com -DefaultPublicFolderMailbox "myname.COM/Users/All Public Folders"
