This post is about a recent migration of legacy public folders hosted on Exchange Server 2007 to modern public folders hosted on Exchange Server 2013.
When designing for a migration to Exchange Server 2013, chances are you’ll have to deal with public folders. Given that Exchange 2013 has been around for a while, you might think such a task would be a proverbial walk in the park. Of course, if you are looking at a cookie-cutter environment, you might be right. However, in every design there are elements specific to the customer that require a different approach.
More specifically, consider the scenario in which you have public folders — possibly lots of them. For the sake of this article, let’s assume you have about 500GB worth in public folders spread over several thousand public folders across one or more replicas. For some customers, these numbers are much more than they have. For other customers, 500GB in public folders might just be a fraction of what they have to deal with. Regardless of your situation, public folders raise a rather interesting question: How do you plan for (a migration of) public folders to Exchange 2013?
Exchange 2010 Public Folders allow your administrators the ability to grant specific users the ability to send mail on behalf of a mail-enabled public folder.
Before we look at the Manage Send As issue, let’s take a look at how an Exchange or Security administrator would adjust the mail-enabled Public Folder Send As Permissions.
How to Manage the Public Folder Send As Permissions
- Open the Exchange Management Console
- Click the + to the left of Microsoft Exchange On-Premises
- Click the Tool Box
- Double-click Public folder Management Console
- Select the public folder that you would like to adjust the Send As Permissions on
- On the right-hand side of the screen choose Manage Send As Permission
What is ExFolders?
ExFolders is a Microsoft tool that can connect to Exchange 2010 public folders through a GUI and is separate from the Exchange Management Console. This tool has replaced the old PFDavAdmin public folder administration tool that was used with older versions of Exchange. Microsoft has added some backward compatibility within ExFolders and has configured it to work with Exchange 2007, but it must be run from an Exchange 2010 server. This powerful tool can recover deleted public folder items, propagate public folder permissions, manage your public folder replicas, modify public folder size limits, and more. I like to think of using this utility as a way to get “under the hood” to gain additional insight into the configuration of your public folders.
Getting Started with ExFolders
Now that we know what ExFolders can do, you might ask "how do I get started?" Before you begin, if you are running Exchange 2010 SP1 or later you will need to download the latest ExFolders from http://gallery.technet.microsoft.com/office/Exchange-2010-SP1-ExFolders-e6bfd405. This will need to be installed on an Exchange server, preferably the server with your primary public folder database. Download and extract this to "C:\Program Files\Microsoft\Exchange Server\V14\Bin”. If an older version of ExFolders exists in this directory it is ok to overwrite.
