Hello, I have a situation where an organization has asked me to remove access to individual calendars to force them to use a shared or group calendar instead so that User A cannot access or cannot use his own calendar, but must instead use the shared calendar of user B or Group Calendar C to post meetings, etc.... It seems that the cmdlet Remove-MailboxFolderPermsission -identity userA:\calendar -user userA will not remove permissions of the mailbox owner. (Unless there is a switch I'm unaware of?) That said, is there a way to accomplish what is being asked of me? Personally, I think they are trying to solve an HR issue with technology, but I want to make my client happy and this is a technically interesting task! Thank you for your insight and assistance!

Thank you very much for your reply Martina -- are you quite certain it cannot be done? Does anyone disagree or have ideas for creative workarounds to accomplish the task?

There's a not-so-pretty way to do this. You could give this user a second mailbox with the appropriate permissions to the first. You'd have to iron out things like how the user sends mail, contacts, and a few other issues, some of which could be handled with transport rules.

Thank you very much for your reply Martina -- are you quite certain it cannot be done? Yes, I'm 100% sure. It can't be done.Martina Miskovic
