I have Exchange 2010 SP2. all of sudden, every user in the organization, can now see the Subject in Free\Busy for everyone. I am unclear how this could have happened. Although, everyone had "availabeonly" for their calendar, I went ahead and ran the "Below" anyways, to change everyone to "availableonly". If I go into OWA, you can't see the subject in Free\Busy. However, you can in the Outlook Client. I am puzzled as to why, could there be a RBAC that is controlling this ? If so, what role, assignment ? $allmailbox=get-mailbox Foreach ($item in $allmailbox){ Set-mailboxfolderpermission identity ($item.alias+:\calendar) user Default Accessrights AvailabilityOnly } Thank you

Do the users have read right on the calendar folder?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

How about mailbox rights? Are the users in a super group of some sort?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Here is an example user from both PFadmin and Powershell

Ahh, I was unaware of this. If a member is part of the following groups, are they allowed to see all subjects in Free\Busy ? Maybe I am mistaken, when I was originally told of the issue, it was a select few in the IT staff telling me they could see all calendars free \ busy Subject. I took there word, it was everyone. I will certainly have to review "all users"... Exchange Organization Administrators Exchange Servers Organization management

Hello, From the result, the permission on the calendar folder seems correct. Please verify if the user have the full access permission on mailbox. Cara Chen TechNet Community Support

thanks again.. it turns out... there were some inherited permissions for some of the (IT Staff) users in exchange.. Prior to migrating to Exch 2010, System Admins their "user" accounts, was also there "protected account" . This practice was changed, so now System Admins have a seperate "protected account". I went into ADSIEdit, Configuration > Services > Microsoft Exchange > Organization > Administrative Groups > Exchange Administrative Groups : and removed the accounts in question from security. Waited 15mins, and then Ran the following. Get-Mailbox -ResultSize Unlimited | Remove-MailboxPermission -User "username" -AccessRights Fullaccess -InheritanceType all This seemed to clear it up. Thank you for your time...
