Migrate distribution lists to Office 365 Groups

Distribution group management is quite challenging when it comes to Office 365. Managing a Distribution group needs to be done On Premises if you are synchronizing your Distribution groups to Office 365. A migrated user will not be able to manage the groups he own easily as before and rely on additional mechanisms as outlined here. In order to mitigate this challenges some Admins delete and re-create these groups in cloud as explained here with the exception of Security Enabled distribution groups that still have On premises access dependencies. Managing Cloud based Distribution Groups is explained here. Not just the cloud based Distribution groups are suffice for today's needs in this Agile and Collaborative world, its time to adopt the Modern Groups aka Office 365 Groups.


Unlike traditional Distribution Groups, Office 365 Groups provide much more as explained in detail in my earlier blog post curated with references and latest updates "Office 365 Groups Overview, Administration and Roadmap in a NutShell"

I wrote this article today to give a quick refresh on the topic and refer you to the latest support article published that helps you to migrate Distribution lists in Cloud to Office 365 Groups.

You can migrate your Distribution groups to Office 365 groups provided they are Cloud-managed, simple, non-nested distribution lists.

Microsoft team has provided a list of PowerShell scripts that make your migration smooth, You can identify the eligible groups for migration using the Get-DlEligibilityList.ps1 script and refer the table that lists which distribution lists are eligible or not eligible for migration.

Identify the eligibility criteria for the migration and make sure you edit your existing Distribution groups accordingly if you need them to be migrated to an Office 365 Group.
