This is not a complicated procedure if you are doing it every week or so. I’m doing this once a month and never remember the proper sequence and all the checkboxes. This article describes the way how to send an e-mail as public folder in Exchange 2003
Any mail-enabled object in Active Directory can be used to send e-mail as this object and to send e-mail on behalf of this object. First, let’s find the difference between Send As and Send On Behalf. The article by Jim Boyce (http://articles.techrepublic.com.com/5100-10878_11-5035124.html) explains it clearly.
Long story short: Send On Behalf says who sent the e-mail and on behalf of whom it was done. Send As looks like e-mail sent by that person or object and there is no information about the real sender.
Since mail-enabled public folders are used for communication between a requestor and group of people (technicians, service desk, etc), Send As is a better approach if we need to reply to the e-mail came into public folder.
How to set up Send As for public folder
Create a mail-enabled public folder. I called my folder Admin
Right-click on the folder name and select Properties
On the General tab enter the Public folder description and Address list name. This is the name the public folder will be presented under in address book
Go to the Exchange Advanced tab
Clear the Hide from Exchange address lists checkbox. Send As does not work if public folder is not visible in Address Book
Go to the Permissions tab
Click on the Client permissions button, add a user and give the user the ability to read and create items
Click on the Directory rights button, add the user and give the user the SendAs permission. Just SendAs is enough
Click OK to close the folder properties.
Almost done. However, it will not work until the public folder is in Address Book.
- Rebuild the Default Offline Address List in Exchange System Manager
- In Outlook select Tools –> Send/Receive –> Download Address Book. After process finishes, check out if the public folder is visible in address book.
