1. Group definitions
1.1. Security Group
A security group is a collection of user accounts, computer accounts, service accounts, or other security groups that are created for the purpose of managing access permissions. These groups are used to simplify the administration of access to resources such as files, folders, SharePoint sites, and other elements within the Microsoft 365 ecosystem.
1.2. Microsoft 365 Group
A Microsoft 365 Group is a collaboration feature that brings together people, conversations, and tools. It includes a shared mailbox, calendar, file repository, and more, fostering seamless communication and collaboration.
1.3. Distribution List
A Distribution List is a mail-enabled object used for sending emails to a predefined list of recipients. It simplifies communication by allowing you to email multiple people using a single group email address.
1.4. Mail-Enabled Security Group
A Mail-Enabled Security Group combines the features of a security group and a distribution list. It allows for both security-related functions, such as permission assignments, and distribution of emails.
2. Creating Groups in Microsoft 365
Ah, Microsoft, the maestro orchestrating the digital circus, where consistency is like a rare Pokémon – hard to catch. If Microsoft decided to make all their admin centers sing the same tune, we might question if we accidentally stumbled into a tech Twilight Zone. In the Azure Active Directory (Azure AD)/ Entra portal, it's a smooth cha-cha for creating Security Groups and Microsoft 365 Groups – a dance into the world of permissions. Now, shimmy over to the Microsoft 365 Admin Centre, the admin equivalent of a buffet, serving up Teams, Microsoft 365 Groups, Distribution Lists, Security Groups, and Mail-Enabled Security Groups. Admin life, a delightful mix of options, right? But hold on, the Exchange Admin Centre has its own VIP lounge, exclusive for crafting Microsoft 365 Groups, Distribution Lists (dynamic ones included), and Mail-Enabled Security Groups. Who needs consistency when you can have an admin fiesta with all the groups? Microsoft, you sly admin trickster, keeping us grooving to your beat! 🕺💻
Behold, the navigational roadmap! The table below offers a visual compass, guiding you through the eclectic landscape of Microsoft 365 admin centers, highlighting where each group creation magic happens. 🗺️✨

3. Understanding Group Nesting
Group nesting involves placing one group inside another, creating a hierarchical structure. This arrangement aids in managing permissions and communication within an organisation effectively.
4. Key points about group nesting
Security groups can be nested with another security group via the Azure AD/ Entra portal and Microsoft 365 admin centre.
Microsoft 365 Groups cannot be nested with any other group.
Distribution groups can be nested with another distribution group, but only through the Exchange Admin Centre or Microsoft 365 Admin Centre.
Mail-Enabled Security Groups can be nested with another Mail-Enabled Security Group, but only through the Exchange Admin Centre or Microsoft 365 Admin Centre.
5. Group Nesting Limitations
Security groups cannot be nested with a Microsoft 365 Group nor a Distribution List.
You can nest a Security Group with a Mail-Enabled Security Group (only via Azure/Entra portal or Microsoft 365 admin centre).
Microsoft 365 Groups cannot be nested with Distribution Lists or Mail-Enabled Security Groups.
Distribution Lists cannot be nested with Microsoft 365 Groups.
You can nest a Distribution List with a Mail-Enabled Security Group (only via Exchange Admin Centre or Microsoft 365 Admin Centre).
