I have upgraded my HMC4.0 to Exchange 2007 Sp1 with the patches mentioned in JasonJoh's Blog. Everything is fine except nothing difference in OWA!

And I get-CASmailbox, I got,

OWARulesEnabled                       : False
OWAPublicFoldersEnabled               : False
OWASMimeEnabled                       : False
OWARecoverDeletedItemsEnabled         : False

 Therefore, I modify my user plan to this,

          <owaRulesEnabled>1</owaRulesEnabled>
          <owaPublicFoldersEnabled>1</owaPublicFoldersEnabled>
          <owaSMimeEnabled>1</owaSMimeEnabled>
          <owaRecoverDeletedItemsEnabled>1</owaRecoverDeletedItemsEnabled>

The provtest run properly, but when I provtest getUserPlan.xml, I can't find such fields!!! And of course, I don't see any new features in my OWA although the version of OWA is updated!!

 So, does it mean HMC4.0 not fully support Exchange 2007 SP1?? Or more patches needed?? Or I got the wrong sequence of the patches did??

Please help! Thanks a lot!!!

Did you read white paper, published by MS couple days ago? http://forums.asp.net/t/1213293.aspx

It has an answer to your question (Page 6, last paragraph):

"Note: OWA Premium version for user mailboxes must be explicitly enabled to use new OWA features such as Rules Editing and public folder access.  Because OWA feature settings are explicitly specified within HMC 4.0 provisioning APIs, currently it is not possible to specify these new OWA settings through HMC 4.0 provisioning APIs.  Hosted service administrators can call Set-CASMailbox cmdlet explicitly to enable the new settings after a mailbox has been provisioned using HMC provisioning service.  Service Providers should test it thoroughly to verify the impact."

You can set the value of msExchMailboxFolderSet with this value 125828991 . All the feature will be enabled.

If you use the set-CASMailbox cmd-let it will drop other attributes set by MPS.  The public folders will appear in OWA, but the user will have trouble logging in with the Outlook 2007 client.  Upon configuration of the mailbox with autodiscover we see the error "the username cannot be matched to the address list".   Of course you can then use the repair function of MPS to fix the loss of the attributes and it's all ok again.

 It works, but it's kinda like a real dirty way of working if you ask me?

Is this value confirmed? If you don't mind me asking, where did you get the values for Ex2k7? (could only find 2k3).
Did you set this though an MPS provider or through ADSIEdit?

Thx in advance!
