I was wondering if anyone could help me diagnose why 4 of our 5 PF's are not updating (no new emails showing) since the update was performed?

Everything seems correct when I check the properties within EAC for each PF, to note they match the working PF.

Thanks in advance!

Hello,

With CU6 there is a big change in how Public Folders accepting mail.

"Mail-Enabled Public Folder Permission Changes

This is an important change for customers already using Public Folders in Exchange Server 2013. Prior to CU6 unauthorized senders were able to send messages to mail-enabled Public Folders which means external users could send email to mail-enabled Public Folders regardless of permissions. With CU6, administrators must grant Anonymous users Create Items permissions in the mail-enabled Public Folder to allow external users the ability to send email to the mail-enabled Public Folder. Refer to the CU6 release notes Public Folders section for guidance on updating your configuration."

"Starting with Exchange 2013 CU6, if you want external senders to send mail to a mail-enabled public folders, the Anonymous user needs to be granted at least the Create Items permission. If you've set up mail-enabled public folders and haven't done this, external senders will receive a delivery failure notification and the messages won't be delivered to the mail-enabled public folder."

Hopefully this will help to resolve the problem.

Superb thanks!!

Ref;

Add-PublicFolderClientPermission "\Customer Feedback" -AccessRights CreateItems -User Anonymous
obviously change "customer feedback" to your own public folder name.
Thanks again.
