Export Office 365 Nested Distribution Group Members using PowerShell
A Distribution Group is used to send emails to multiple recipients at once (both internal and external users) that are particularly significant for providing support to users. Efficiently adding members to the Distribution group is crucial to maximizing productivity.
Managing more efficiently the distribution groups comes with the use of nested distribution groups. In this blog let me guide you through to know what are nested distribution groups, where they can be used, and how to export nested distribution group members.
Adding a distribution list to another distribution list is defined as a Nested Distribution List. Nested distribution lists are intended to aid in,
- Minimizing the replication traffic within the tenant. If you’re looking out to send the same messages to multiple groups, you can start using nested distribution lists.
When the members of the groups are known, we can determine whether the users are in the correct group or not. It is therefore imperative to export the members of the group.
Exporting Office 365 Distribution Group Members is easy, but what about exporting nested distribution group members?
To Export the nested distribution group members’ details are one of the foremost errands to work. It takes a long time to acquire information because you have to navigate each group. As a result, the GUI mode is unable to export the information.
PowerShell comes in handy here! The Get-DistributionGroup and Get-DistributionGroupMember cmdlets let you retrieve direct members only. If you want to retrieve nested distribution group membership, you’ll need to loop through multiple cmdlets and filters, but this process is a bit hectic.
Thus, our PowerShell script made this task much facile for you! With two types of reports provided by our script, you can get deep insights into your nested distribution group membership.
