all users modifying all calendars?


I am working with Exchange 2010 serving about 70 users. My boss wants all users to be able to edit all calendars. I mean everyone able to move appointments around and create events on anyone else's calendars. Is this even possible? it does not sound like a good idea to me. If it is possible, how would it be done?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

For the sake of security it is not a valid task, but still if you want to this follow below powershells:

You can do by below powershells

$allmailbox = Get-Mailbox -Resultsize Unlimited

Foreach ($Mailbox in $allmailbox) {Set-mailboxfolderpermission –identity ($Mailbox.alias+':\calendar’) –user Default –Accessrights Reviewer}

Open in new window

Once it is done for all, so you can schedule it weekly like users are created in last 7 days will share calendar.

$allmailbox  = Get-Mailbox -resultsize unlimited | where {$_.WhenCreated -gt (get-date).AddDays(-7)}

Foreach ($Mailbox in $allmailbox) {Set-mailboxfolderpermission –identity ($Mailbox.alias+':\calendar’) –user Default –Accessrights Reviewer}

Open in new window

This looks good. So I would just run this script on my Exchange server jsut as it it written? Nothing needs to be changed?

I had one more question: can I change the work "reviewer" and substitute "editor" since I want people to have all rights?
