After Mailbox Move to new Store, users cannot access resource mailboxes

Recently we have had to move mailboxes from on Information Store to a new one.  We have almost completed the process when it was brought to my attention that users who are assigned access to mutiple mailboxes cannot open secondary resource mailboxes.  For example, if John Doe(JDoe@xyz.com) open his profile and then attempts to open the Help Desk (helpdesk@xyz.com) he gets the error "Unable to expand the folder. Microsoft Office Outlook could not access the specified folder location."  In this case both mailboxes have been moved to the new information store.  But if John attempts to open a resiource mailbox with the same exact AD permissions in the old information store it opens right away without issue.

This article describes our problem and the solution to our problem.  I do not know why or how this setting got turned off during the mailbox move.  We have about 500 resource mailboxes and we need to do as quickly as possible.  Is there any way to do this with out creating a profile for each box and changing the settings?

Please let me know if you require any additional information.

Thanks.

Setperms did not work in our situation.  We ended up calling Microsoft and they pointed us to this KB article http://support.microsoft.com/kb/922617.  Once we installed the associated HotFix we still were not able to use permissions set at any Exchange level, but the settings at the Mailbox Rights level within AD started working again and everybody's access was restored to the resource mailboxes.

Thank you all for your help and input.

If the Information store is reading off the same domain controller/domain then it definitely is strange that the mailbox rights did not come accross.

In saying that, you can use a tool such as ADModify to bulk add users to resource mailboxes.

An interesting article on using ADModify an be found here - http://www.msexchange.org/tutorials/Using-admodifynet-administer-recover-Exchange-2003.html

You can download the tool from here - http://www.computerperformance.co.uk/ScriptsGuy/ADModify_2.1.zip

While this applies to Exmerge, it does have a method in restoring the delegate folder permissions.

How did you 'move' the information store?

All the delegation permissions and AD permissions remained in tact and were not modified at all.

I moved individual mailboxes, not the entire information store by selecting the mailboxes that I wanted to move clicking Exchange Tasks and Move Mailbox, then select the the information store where I wanted the mailbox to reside.
