Knowing Which Clients Work with Delegate Access

We often use delegate access in our organization. We're about to migrate to Microsoft Exchange Server 2003. Which clients will work with delegate access?

Here's a quick rundown of popular Exchange clients and whether they support delegate access when used with Exchange 2003:

• IMAP and POP clients don't support delegate access.
• Microsoft Entourage 2004 for Mac OS X supports Outlook-style delegate access but doesn't support setting up delegation: The mailbox owner has to use Outlook for Windows to grant delegate permissions.
• Outlook 97 and later all support delegate access via Messaging API (MAPI).
• Outlook Mobile Access (OMA) and Exchange ActiveSync don't support delegate access.
• Outlook Web Access (OWA) doesn't support delegate access, but OWA users can get around that restriction by using the direct URL for the delegated mailbox they want to access.
