Distribution Groups to Microsoft 365: An Overview

To efficiently manage Distribution Groups directly in Exchange Online after migrating mailboxes, administrators must undertake a meticulous process to ensure seamless integration into Microsoft 365. The process involves exporting the on-premises Distribution Groups to a CSV file, which requires careful editing to match the required attributes for Microsoft 365. PowerShell scripts play a crucial role in creating and modifying these groups within the new environment. It includes importing the groups while keeping them hidden from the Global Address List (GAL) until the migration is verified to have been correctly executed.

 

Migrating Distribution Groups to Microsoft 365 after transitioning mailboxes to Exchange Online can be challenging as they remain on-premises. This guide outlines an effective process for relocation to Exchange Online, allowing for direct management within Microsoft 365. Additionally, it emphasizes the importance of all mailboxes being in Microsoft 365 before attempting migration.

• Export on-premises Distribution Groups to a CSV file.
• Manually edit the on-premises Distribution Groups CSV file to ensure accuracy.
• Import Distribution Groups into Microsoft 365, using PowerShell for automation.
• Add members to the newly created Distribution Groups in Microsoft 365.
• Move Distribution Groups to a separate Organizational Unit if necessary.
• Unsync original on-premises Distribution Groups from Microsoft 365.
• Finalize the process by removing prefixes and hiding groups from the global address list as needed.
• Test mail flow to ensure Distribution Groups are functional.

Through these steps, Distribution Groups are recreated in the cloud, allowing for seamless integration into Microsoft 365's environment. This detailed migration strategy ensures the continuation of group functionalities, securing an organization's communication channels in the cloud.

Adding members to these groups and ensuring the correct settings are in place for visibility and email flow constitutes the core of the migration process. It requires attention to detail, especially when editing the CSV file and running the PowerShell scripts, to avoid common pitfalls that could lead to errors or incomplete migrations. Microsoft 365 allows for streamlined management and operation of Distribution Groups post-migration, but achieving this state demands a thorough, step-by-step approach guided by best practices and a deep understanding of both the on-premises and cloud environments.
