How to use Powershell to set delegate for user mailbox in Exchange 2010 and Office 365

Question

Hello,
Can you please tell me if I can set delegate for user mailbox in Exchange 2010 or Office 365 using Powershell?
If I can, then how can I do that? (which Powershell commands for setting the delegate?)
Many thanks, and have a good day!

Hi,
If you wanted to add a delegate to possiblly a large number of users or you do this during mailbox provisioning. So the following script will use
impersonation to access another users mailbox and add a delegate.
$mbtoDelegate = "[email protected]"
$delegatetoAdd = "[email protected]"
$dllpath = "C:\Program Files\Microsoft\Exchange\Web Services\1.0\Microsoft.Exchange.WebServices.dll"
[void][Reflection.Assembly]::LoadFile($dllpath)
$service = new-object Microsoft.Exchange.WebServices.Data.ExchangeService([Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2007_SP1)
$windowsIdentity = [System.Security.Principal.WindowsIdentity]::GetCurrent()
$sidbind = "LDAP://<SID=" + $windowsIdentity.user.Value.ToString() + ">"
$aceuser = [ADSI]$sidbind
$service.AutodiscoverUrl($aceuser.mail.ToString())
$service.ImpersonatedUserId = new-object Microsoft.Exchange.WebServices.Data.ImpersonatedUserId([Microsoft.Exchange.WebServices.Data.ConnectingIdType]::SmtpAddress,
$mbtoDelegate);
$mbMailbox = new-object Microsoft.Exchange.WebServices.Data.Mailbox($mbtoDelegate)
$dgUser = new-object Microsoft.Exchange.WebServices.Data.DelegateUser($delegatetoAdd)
$dgUser.ViewPrivateItems = $false
$dgUser.ReceiveCopiesOfMeetingMessages = $false
$dgUser.Permissions.CalendarFolderPermissionLevel = [Microsoft.Exchange.WebServices.Data.DelegateFolderPermissionLevel]::Editor
$dgUser.Permissions.InboxFolderPermissionLevel = [Microsoft.Exchange.WebServices.Data.DelegateFolderPermissionLevel]::Reviewer
$dgArray = new-object Microsoft.Exchange.WebServices.Data.DelegateUser[] 1
$dgArray[0] = $dgUser
$service.AddDelegates($mbMailbox, [Microsoft.Exchange.WebServices.Data.MeetingRequestsDeliveryScope]::DelegatesAndMe, $dgArray);
Hope this helps.
