Nesting Groups in Office 365


Nesting Groups has been a bit of a pain in Office 365 for a while now but there's apparently a few answers (and some updates on the way).  

Here's a PowerShell method. 

The Setup

To start with, we're going to create a group in Office365 Admin. It should be a mail enabled security group.

In our example the group will be called;

GRP MotherGroup
and it will have an email address of MotherGroup@mydomain.com
(obviously the domain will be different at your location).

For the purposes of this exercise, you'll also want to create several groups to be nested.
These are distribution groups and their names and emails for the purposes of our demonstration will be;
GRP BabyGroup1  babygroup1@mydomain.com
GRP BabyGroup2  babygroup2@mydomain.com
GRP BabyGroup3  babygroup3@mydomain.com
GRP BabyGroup4  babygroup4@mydomain.com


The PowerShell Commands

As usual, you'll want to run PowerShell in Administrator Mode.

Set-ExecutionPolicy RemoteSigned
Press Y and Enter.

$UserCredential = Get-Credential
You'll be prompted to logon with your user name and password.  If you have multi-factor authentication enabled, you'll probably have a few extra hoops to jump through here.

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication  Basic -AllowRedirection

This creates the session

Import-PSSession $Session

This activates the session.

The next command is specific to your group. It looks like this (boldfaced parts will be replaced).

Add-DistributionGroupMember -Identity -Member


If you're following our example, the commands would be as follows;
Add-DistributionGroupMember -Identity MotherGroup@mydomain.com -Member babygroup1@mydomain.com
Add-DistributionGroupMember -Identity MotherGroup@mydomain.com -Member babygroup2@mydomain.com
Add-DistributionGroupMember -Identity MotherGroup@mydomain.com -Member babygroup3@mydomain.com
Add-DistributionGroupMember -Identity MotherGroup@mydomain.com -Member babygroup4@mydomain.com


As usual, because we're neat people, we remove our session before exiting...
Remove-PSSession $Session
Exit

If you go into the Office 365 Admin console, you should be able to find your group, now with the nested subgroups below it. It's a painful process but it works.

How to Change Your Notification Options for New Lotus Notes Mail in version 8.x

Don't worry, I'm not patronizing you (my readers), I just decided to re-document this for one of our internal users and thought you might want to be able to use it in your own user documentation. WHAT IS THIS DOCUMENT ABOUT? Some people who don't get a lot of mail, like to be notified when such an event occurs. Notification can be; via a sound via a pop-up box via the system tray (where the computer clock is) The pop up box looks like this; Other people, who like myself, get too much mail would rather not be notified. The aim of this document is to tell you how (and where) to turn these options on and off. CHANGING YOUR SETTINGS To change your settings from the Notes 8.x client; On the Menu, click File , then Preferences... On the left hand side , click on the little plus sign to the left of Mail to expand the options. Click on the option marked Sending and Receiving . In the middle section, under receiving, you can control your notifications. If you untick the box mark...

How to Create a Bootable DVD Using Nero Burning ROM 9

I often need to create bootable CDs and DVDs but it's weird because I frequently end up buring myself a new coaster instead. It's not that the process is difficult, just that nero has a few too many options and I forget which ones to choose and end up picking the wrong one. I figured that the best way to avoid this mistake in future would be to write the steps down. Procedure Insert CD or DVD into your DVD Burner. Start Nero Burning ROM 9 Choose DVD-ROM (Boot) or CD-ROM (Boot) depending on what you're creating You'll be prompted for a disk image source. Choose a Nero Source - you'll usually find them somewhere like this... C:\Program Files\Nero\Nero9\Nero Burning Rom\DOSBootImage.ima Leave the Boot Locale as English - unless you really need a different keyboard layout Tick the box marked [X] Enable Expert Settings Choose Hard Drive Emulation and leave any other settings as they are. Click the button marked New Add any files you want but don't try to add operati...

How to Create an Auto-Response Mail Message in Lotus Notes 8.5.3+

Why would you do this? Suppose that you have an externally accessible generic email address for your company; support@mycompany.com or info@mycompany.com. You might expose this to the web and allow people to send messages to you. Setting up an auto-response email will tell the senders that their message reached its destination and that it will be dealt with accordingly.  It's also good practice to include links to FAQs or other useful information. Why 8.5.3 The techniques we'll be using here work in older versions of Notes but some of the options seem to have moved around in 8.5.3.  I figured it was a good time to show you where they've moved to. The Procedure Start Domino Designer and open the Mail file to be modified.  A really quick way to do this is to right-click on the application tab and choose "Open in Designer". In the Left hand panel of designer, expand Code and then double-click Agents.  A new window should appear. Click the action ...
