New Post: PR_ATTR_HIDDEN in Shared Mailbox

I have an Office 365 account, and I am trying to hide the Calendar folder in a shared mailbox. We have a bunch of users that need a shared Inbox, but don't care about the calendar, so I'm trying to prevent just the Calendar from automatically showing up in Outlook. (They all have full access to the mailbox, so it is automapped). We have this same request over multiple shared mailboxes.

When I set the value of PR_ATTR_HIDDEN to true, it works great...except it seems to only apply for the account I am logged in as.

Is there a way to do this so that all users that connect to the shared mailbox do not see the calendar folder, without having to set the hidden attribute for each individual user account that connects to the mailbox?

Thanks!
