This can only be view from OWA 2010 or Outlook 2010.

Integrated e-mail archive   The Personal Archive feature is available with Outlook 2010 and Exchange Server 2010 and lets you regain control of the organization's messaging data by eliminating the need for Personal Folder files (.pst). Like .pst files, the Personal Archive feature does not affect the user’s primary mailbox size. However, unlike .pst files, the e-mail archive folders are stored online so that users can access the archived files by using Microsoft Outlook Web App or from a secondary computer by using Outlook 2010. By using either of these client applications, users can view an archive mailbox and move or copy messages between their primary mailboxes and the archive.

just going to confirm, this is feature can only be accessed using Outlook 2010 or the Exchange 2010 Outlook Web App

That is correct.

i was reaffirming your post :) or seconding it so to speak

According to the person I talked to at Microsoft prior to commiting to Exchange 2010, the archives were available to Outllok 2010 or Outlook 2007.

they misinformed you as this was never the case

The plugin for Outlook 2007 has not yet been released to correct this problem. This statement was made as of 9/15/2010.

Well we have it installed and it's great and then we found out that our Outlook 2007 users have no access to the archives (I'm sure I saw a video of one of the team stating that it would be available at release).

Is there a definitive answer from MS on when an update or plugin will be available for Outlook 2007? We cannot afford to move everyone to 2010 just for this feature.

@jtd1 in fact the person who informed you was right, it was planned to release support for archive mailboxes on outlook 2007 with exchange 2010 SP1 and it was a very hot topic that even appeared on the exchange team blog itself.

Unfortunately Microsoft had to rush things and release SP1 earlier than predicted so they kept this feature out, they promised it will be up by early 2011 though

Office 2007 Enterprise supports it, along with Office 2010 Pro Plus, and outlook 2010 volume license.
