Office 365 – Migrating Distribution Groups

Summary / Problem Statement

When an organization completes an Exchange Online migration, any distribution groups that remain DirSynced from Active Directory become unmanageable in the cloud.
Common symptoms include:
Users can no longer edit group membership in Outlook.
Azure AD–synchronized groups can’t be modified in Exchange Online.
Adding external contacts requires on-prem directory objects.
Rather than rebuild these manually, the following PowerShell script automates a full, safe conversion of on-premises distribution groups into native cloud objects.
Overview of the Script

The script performs the following workflow:
Connects to Exchange Online PowerShell (MFA-aware).
Creates working and export directories for backups.
Backs up all synchronized distribution-group attributes and memberships to CSV.
Builds cloud copies of each group, prefixed with Cloud_.
Removes the original on-prem groups.
Triggers an Azure AD Connect delta sync.
Renames the new cloud groups back to their original names.
Re-enables the sync scheduler.
Average run time: ≈ 20 minutes for typical tenants.
Note:
The script is designed for execution on the domain controller running Azure AD Connect.
It excludes mail-enabled security groups.
Usage

Run in an elevated PowerShell session.
Requires ExchangeOnlineManagement and ActiveDirectory modules.
Always review backups before deleting on-prem groups.

## Name:        DG_Cloud.PS1
##
## Version:     1.0
##
## Description: $ Installs required components for Exchange Online Powershell Management
##              $ Creates a "Working" folder (C:\PoSH-Working) for backups.
##              $ Creates an "Exports" folder for the temp files needed to migrate the
##              Distribution Lists.
##              $ Backs up the Distribution List Names and Attributes to DG_Details_Backup.csv
##              $ Backs up the Distribution List Members to DG_Members_Backup.csv
##              $ Capable of running mulitple times and retaining existing backups - creates
##              new backups each time it's run if any new groups are detected
##              $ Selectively Creates a copy of each Distribution Group called Cloud_$Group
##              that are specifically Distribution Groups and not Mail-Enabled Security
##              groups.
##              $ Deletes the selected Distribtuion Groups from Active Directory
##              $ Initiates an Azure AD Connect to remove the AD objects from Cloud Environment
##              $ Forces wait period of 5 minutes to allow Azure AD to synchronize with Exchange
##              $ Completes process by renaming Cloud_$Group back to original name
##
## Usage:       Execute script in PowerShell with elevated privileges
##
## Author: Jason Zondag
##
## Disclaimer:  Has not been tried in every conceivable environment - always check the results
##              and fall back on the backups created to recreate the Distribution Groups if
##              necessary
