I have converted my script that displays a mailbox’s delegates into a module that adds the ability to add, modify, and remove a mailbox’s delegates. The benefit of the module is that it negates the need to create an Outlook profile for the owner/manager in order to manipulate his or her delegates. The module requires any version of the EWS Managed API and the Exchange cmdlets via remoting, as detailed below.

Upon importing the module, it will check for any version of the EWS Managed API, starting with version 2.0 and working its way back. This allows for the freedom to have any version installed instead of requiring everyone who uses it to ensure they have the specific one I used when writing it. After the API is loaded, it will check for the Exchange cmdlets. If not loaded into the shell, it will retrieve a list of Exchange servers from Active Directory and attempt to connect to one until successful. If neither the API nor remoting to Exchange is successful, the module will fail to load, telling you why. (The module doesn’t distinguish between the cmdlets being available because they were locally loaded from the snap-in or from remoting. However, since certain cmdlets will fail when not executed remotely because they bypass RBAC, you need to be sure that you have not locally loaded the snap-in.)

Access to a mailbox is done using impersonation by the person running a cmdlet. If you won’t be using impersonation, instead relying on full mailbox access, you will want to comment out line 94. The URL used for EWS is determined by autodiscover of the owner/manager mailbox.

These are the cmdlets the module exposes:

Get-MailboxDelegate

The alias for Get-MailboxDelegate is gmd.  It is basically the same as my Get-Delegates.ps1 script, but it has gotten a makeover to support pipelining into and out of. The -Identity parameter (aliased to -Owner and -Manager) is any standard Exchange identity (display name, email address, alias, dn, etc.) and it supports pipelining by property name. If the objects you are pipelining into Get-MailboxDelegate don’t have a property name of Identity, then you will need to use a ForEach loop and use $_.PropertyName to designate which property should be used.

Without any other parameters, all delegates will be retrieved. If you want to get only a specific delegate, you can use the -Delegate parameter. The default output will be to list the properties, but since it is now a collection of objects, you can choose to output it to a table, to a grid view, or export to a file, using the appropriate cmdlets. You can also use these output cmdlets to select only the properties you want. For example, if you only care about the private items property you could use ft owner,delegate,viewprivate. Or, if you only want those who actually can view private items, you could run something like this:

(Get-DistributionGroupMember <DLIdentity>) | gmd | where {$_.ViewPrivate -eq $true} | ft owner,delegate

Note that I encapsulated in parentheses the command that I pipeline into Get-MailboxDelegate. This is necessary to avoid the concurrent pipeline limitation in remote PowerShell. It is only necessary if the command prior to the pipeline will be running a cmdlet that leverages remoting. Another option is to store the results of the prior command in a variable and then pipeline that into Get-MailboxDelegate.

All of the module’s cmdlets have built-in help, so you can use PowerShell’s help cmdlet to learn the details of all of them, such as the parameters and their descriptions, usage examples, etc.

Add-MailboxDelegate

The alias for Add-MailboxDelegate is amd. To use this cmdlet, provide an owner and a delegate. You can optionally specify folder permission for Inbox, Calendar, Tasks, Contacts, Sent Items, and Deleted Items; if private items are viewable; if meeting requests are to be received; and the owner’s global handling of meeting requests. I didn’t include the option of setting permission for Journal or Notes because, well, who uses them? The ability to set the permission for Sent Items and Deleted Items is to accommodate those who use GPO to have Outlook store messages sent from another user in that person’s Sent Items folder, and likewise for messages deleted from another mailbox. The option to set the meeting request delivery scope applies to the owner, not the delegate being added, so it is only necessary to include it if you are adding a delegate and you want to change the current setting.

Set-MailboxDelegate

The alias for Set-MailboxDelegate is smd. Use this cmdlet to change any settings for an existing delegate (or to change the meeting request delivery scope for the owner). Provide the owner and the existing delegate to modify and, optionally, which setting you want to change. All other settings will remain as is. If you want to change just the meeting request delivery scope for the owner, specify any existing delegate, but not any other settings (except the delivery scope). Unlike the valid roles for folder permission with Add-MailboxDelegate, you can use None if you want to remove a folder permission. If you want to remove the ability to view private items or to not receive meeting requests, use -ViewPrivateItems:$false or -ReceiveMeetingRequests:$false, respectively. The colon is necessary because both parameters are switches, so their inclusion alone in the command means true, whereas to explicitly set them to false means using the syntax above. (The cmdlet checks if either switch is actually present in the command, so don’t be concerned that not including a switch implies that it should be false.)

Remove-MailboxDelegate

The alias for Remove-MailboxDelegate is rmd. Provide the owner and the delegate to remove. That’s it.

All of the cmdlets perform the expected error checking: the owner is a valid mailbox; any delegate to add, modify, or remove is a valid mailbox; adding a delegate when the delegate already exists; modifying or removing a delegate that is not an existing delegate; using a valid (albeit the limited subset exposed in the API) role for a folder permission; and using a valid meeting request delivery scope.

As part of the patch and reboot script I use in my Exchange environment, there is a separate script that runs Windows Update, first covered here.  I have updated the script to allow skipping the installation of any patches by specifying the KB numbers in a companion file.

Starting on the second line of the file (so that the first line can contain instructions), list one KB number per line.  To use this list, there is a new function in the script:

function Get-UpdatesToSkip
	{
	$scriptDirectory = Split-Path $script:MyInvocation.MyCommand.Path
	$KB = @()
	if (Test-Path "$scriptDirectory\updatestoskip.txt")
		{
		$sourceFile = Get-Content "$scriptDirectory\updatestoskip.txt"
		if ($sourceFile.Length -gt 1)
			{
			for ($i = 1;$i -le $sourceFile.Length - 1;$i++)
				{
				$KB += $sourceFile[$i]
				}
			}
		}
	$KB
	}

The function gets the current path of the script, checks for the existence of the file, and reads each KB into an array. If the file is not present, or is present but no KB numbers are listed, the array will just be empty. This allows the script to still run successfully when you don’t have the file or specify any patches to skip.

When searching for available updates via the Microsoft.Update.Session interface, you can’t filter on a KB number, but you can filter on an Update ID (UID). Unfortunately, to cross reference KB number and UID, you have to first perform a search anyway. So rather than searching twice, I just work with the collection created from the search. The object that contains the list of available hotfixes cannot be manipulated the same way as a standard collection object since it is a COM object, so you can’t use a method like Remove() to remove an item from the collection.

Therefore, in order to have a collection of updates that don’t include certain KBs, you can build a new collection, skipping items in the first collection that match a filter. To do this, I create another Microsoft.Update.UpdateColl object that will be used to specify which updates to download (so that you don’t download all of the updates and then skip certain ones):

$updatesToDownload = New-Object -ComObject 'Microsoft.Update.UpdateColl'

To add to this collection, each item in the first collection is compared to the array that contains the list of KBs:

$updatesToSkip = Get-UpdatesToSkip
$updates | ForEach-Object {
	if ($updatesToSkip -match $_.KBArticleIDs)
		{
		WriteEvent "Skipping download of $($_.KBArticleIDs) since it is listed in the file of updates to skip." 'Information' '1001'
		}
	else
		{
		$updatesToDownload.Add($_) | Out-Null
		}
	}

(The WriteEvent function is defined in the script and is used to write a custom event to the Application log so that you will know that an update was intentionally skipped.) The rest of the script is basically unchanged; just some minor tweaks to accommodate the new code. The download has been updated and includes the companion text file. (If you are wondering why a companion file is used, it is because, as part of the Exchange patch and reboot script, the Windows Update script is remotely called via a scheduled task, and there isn’t a way to dynamically specify command line parameters for a scheduled task (without modifying the task itself)).
