Exchange 2010 Adding Mailbox Calendar permissions using PowerShell

  • Article

Consider the following scenario

We have Students and Teachers located on the same Exchange 2010 server.

Default calendar permissions is set to Free / Busy time

A request has come from the teachers department,

All teachers would like to have Reviewer permissions to each others calendar folders.

Now

What is already prepared in this Exchange environment is that all Teachers have their CustomAttribute1 set to Teacher

And a Mail Universal Security Group already exists with the primary SMTP address Teachers@repro.com

To achieve the teachers request. All we need to do is to run the following powershell command.

Get-mailbox -Filter {(CustomAttribute1 -eq "Teacher")} | ForEach-Object {Add-MailboxFolderPermission $_":\Calendar" -User Teachers@repro.com -AccessRights Reviewer}

Permissions needed.

Mailbox folder permissions

Organization Management

Recipient Management

Help Desk

We are done !!!

To remove the permissions we just added.

Get-mailbox -Filter {(CustomAttribute1 -eq "Teacher")} | ForEach-Object {Remove-MailboxFolderPermission $_":\Calendar" -User Teachers@repro.com}

    Hi I have a sample code $users=Get-Mailbox -resultsize Unlimited ForEach ($user in $users)               {Set-MailboxFolderPermission -Identity $user":calendar" -user Default -AccessRights Reviewer} which changes this for all user mailboxes default permissions to reviewer. Do you think there are any pros/cons against this approach? thanks

    This is an easier way to use this command. Get-content C:tempCalendar.txt | ForEach-Object {Add-MailboxFolderPermission $_":Calendar" -User Teachers@repro.com -AccessRights Reviewer} fill the Calendar txt file with the aliases of users on which the Calender permissions must be set.
