  1. Can the script be modified to grant one group editor rights to all calendars? At work we want the Secretary group to be able to edit all calendars. I’m not a powershell pro by far so i want to know if this is a quick add-on to the script.

  2. Thanks for this script. I kept getting errors with the “Set-MailboxFolderPermission” command. I had to change it to “Add-Mai;boxFolderPermission”. The error stated “No existing permission entry found for user..”
    ———-

    To Heintraag, here is how I modified the script to add reviewer access for a particular user on all calendars. I jsut did this and haven’t fully tested. I am also not a powershell pro so I hope it works. I think I can probably remove the $test section for my purposes since I don’t have any other languages in my environment.

    ———–
    Write-Host “Please type the alias of the user to whom you want to grant reviewer access on all calendar folders: ” -nonewline
    $reviewer = Read-Host

    foreach($mbx in Get-Mailbox -ResultSize Unlimited | where-object {$_.displayname -notmatch “discovery”}) {
    $mbox = $mbx.alias+”:\calendar”
    $test = Get-MailboxFolderPermission -Identity $mbox -erroraction silentlycontinue
    if($test -ne $null){
    Add-MailboxFolderPermission -Identity $mbox -User $reviewer -AccessRights Reviewer | out-null
    [string]$user=$mbx
    [string]$folder=”Calendar”
    [string]$AccessRight=”Reviewer”
    $obj = New-Object PSObject
    $obj | Add-Member NoteProperty User ($user)
    $obj | Add-Member NoteProperty Folder ($folder)
    $obj | Add-Member NoteProperty AccessRight ($AccessRight)
    Write-Output $obj
    }

  3. FYI the title of this page is set as “SCRIPT: Set-CalendarPremissions.ps1” permissions is spelled wrong. I had copied it to save the script locally and was scratching my head when it kept giving errors when I typed it with correct spelling. Thanks for sharing the script, it worked great for me! Cheers!

  4. Do you know how to make this script work when we got multiple users with two mailboxes?
    The alias is the same so I get the “The specified mailbox ******* isn’t unique” when running the script.

    Maybe make it look at the UserPrincipalName instead of alias?

  5. I have changed the script so it determines the Calendar folder name which is useful in a Multilanguage user environment.
