Exchange fellow Jetze Mellema reported something interesting, which he blogged about here. Since you’re not all fluent in Dutch, I’ll blog about it too since it’s important to know when planning your upgrade to Exchange 2010 / Outlook 2010 or during customer engagements.

Until now, blogs mention Exchange 2010’s Personal Archive feature as something for which you’d only need an Exchange 2010 mailbox server (with an archive enabled mailbox)  in combination with Outlook WebApp (OWA) or Outlook 2010 with an Enterprise CAL.

Now, by mentioning “Outlook 2010” it sounds like you can use any version of Outlook 2010 for accessing Personal Archives. Unfortunately this isn’t true. The footnote of this article of the Office 2010 Resource Kit states the following:

Personal Archive is available only when you use Outlook 2010 as part of Microsoft Office Professional 2010 or Microsoft Office Professional Plus 2010 with a volume license.

This poses the question if this will be of influence on current Office 2007 users. As you probably know, the update to enable Personal Archives for Outlook 2007 users is expected 1st half of 2011. Does the above statement imply that only Office 2007 Professional users will be able to use Personal Archives after the update and are Office 2007 Standard users – like Office 2010 Standard users – left in the cold?

I’m afraid I don’t have an answer to that question yet, since there’s no information on that subject. I’ll keep you posted.
