Set calendar-permissions for mailboxes in Exchange Server 2010

I was looking for at way to set default calendar-permissions in exchange 2010, and found out that the only way to do this, is the scripting way.

So i found a script and modified it ( ALOT ) to fit my need

#Load Exchange Server 2010 Management Shell if not loaded.

if (-not (Get-PSSnapin | Where-Object {$_.Name -like "Microsoft.Exchange.Management.PowerShell.E2010"})){
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010

#Custom variables
$mailboxes = Get-Mailbox
$AccessRights = "Reviewer"

#Loop through all mailboxes
foreach ($mailbox in $mailboxes) {

#Retrieve name of the user`s calendar
$calendar = (($mailbox.SamAccountName)+ ":\" + (Get-MailboxFolderStatistics -Identity $mailbox.SamAccountName -FolderScope Calendar | Select-Object -First 1).Name)

#Check if calendar-permission for user "Default" is set to the default permission of "AvailabilityOnly"
if (((Get-MailboxFolderPermission $calendar  | Where-Object {$_.User -like "Default"}).AccessRights) -like "AvailabilityOnly" ) {

Write-Host "Updating calendar permission for $mailbox..." -ForegroundColor Yellow

#Set calendar-permission for user "Default" to value defined in variable $AccessRights
Set-MailboxFolderPermission -User "Default" -AccessRights $AccessRights -Identity $calendar

And then a bat file to execute it from “scheduled task”

powershell -command "&amp; 'C:\PATH-TO-FILE\Set-CalendarPermissions.ps1' "

Lync 2010 Assign Client Policies By Active Directory Groups

After we got our new Lync 2010 setup done, we was missing one key feature.
We want to assign Client policies by Active Directory groups instead of the need to login to Lync admin and change it.

So we made a simple powershell script to do the work for us

save it as Lync-SetClientPolicy.ps1

Import-Module "C:\Program Files\Common Files\Microsoft Lync Server 2010\Modules\Lync\Lync.psd1"
$ADGroupName = $args[0]
$ClientPolicy = $args[1]

$strFilter = "(&amp;(objectCategory=Group)(SamAccountName=" + $ADGroupName +"))"
$objDomain = New-Object System.DirectoryServices.DirectoryEntry

$objSearcher = New-Object System.DirectoryServices.DirectorySearcher

$objSearcher.SearchRoot = $objDomain

$objSearcher.Filter = $strFilter

$objSearcher.SearchScope = "Subtree"

$colProplist = "member"

foreach ($i in $colPropList)

{[void] $objSearcher.PropertiesToLoad.Add($i)}

$colResults = $objSearcher.FindAll()

foreach ($objResult in $colResults)
$objItem = $objResult.Properties;
$group = $objItem.member

foreach ($user in $group)

$userlync= Get-CsUser -Identity $user
if ($userlync.ClientPolicy -like $ClientPolicy)

Grant-CsClientPolicy $user -PolicyName $ClientPolicy


And then a bat file to execute it from “scheduled task”

powershell -command "&amp; 'C:\script\Lync-SetClientPolicy.ps1' "Lync-ClientPolicy-Sales" "Sales" "
powershell -command "&amp; 'C:\script\Lync-SetClientPolicy.ps1' "Lync-ClientPolicy-Default" "Default" "
