Update the public folder hierarchy
Applies to: Exchange Online
Topic Last Modified: 2014-04-03
You only need to update the public folder hierarchy if you want to manually invoke the hierarchy synchronizer and the mailbox assistant. Both these are invoked at least once every 24 hours for each public folder mailbox in the organization. The hierarchy synchronizer is invoked every 15 minutes if any users are logged on to a secondary mailbox through Microsoft Outlook or a Microsoft Exchange Web Services client.

You can’t perform this procedure in the EAC. You must use the Shell.
We recommend that when you run this command with the InvokeSynchronizer parameter, you use the SuppressStatus parameter. If you don't use this parameter in the command, the output will display status messages every 3 seconds for up to one minute. Until the minute passes, you can't use that instance of the Shell.
