Unable to expand to Public folder in mailbox.


Good day

Need help when user try to expand the Public folder and was showing "unable to expand folder".

I had tried to resolve by applying the powershell command in the Exchange management shell and need your help to verify the following command;

get-mailbox -identity username | FL DefaultPublicFolder

Set-mailbox -identity username -DefaultPublicFolderMailbox "domain.net/Services/Public Folders/Accounts/PF"

I assume you are using exchange 2013 as you are setting the default public folder mailbox?

Are you exclusively 2013 or are you in co-existence with 2007\2010?

First off:
get-mailbox -identity username | FL DefaultPublicFolder
Should be:
get-mailbox -identity username | FL DefaultPublicFolderMailbox

Also, the public folder mailbox should just be the name, i.e.
Set-mailbox -identity username -DefaultPublicFolderMailbox "PFMailbox01"

What version of Outlook are you using and what operating system are you using?

What version of Exchange are the public folders on?

Hi Alan,
