Hello, @Narayana V,
Welcome to the Microsoft Q&A platform!
Migrating mail-enabled security groups to Exchange Online can impact SharePoint Online (SPO) and other resources, as these groups often manage permissions. It's crucial to ensure that the groups are correctly synchronized to maintain access control for sites, libraries, and lists in SPO, as well as other applications like OneDrive and Teams.
To identify which sites and applications use these groups, you can use PowerShell scripts. For example, you can list all mail-enabled security groups with Get-DistributionGroup and export their members and owners to a CSV file. This helps in understanding the scope of the migration and ensuring all necessary permissions are accounted for.
The migration process involves preparing the groups in your on-premises Active Directory, synchronizing them with Azure AD, and recreating them in Exchange Online if needed. After assigning members and owners to the new groups, verify permissions in SPO and other resources to ensure a smooth transition. Finally, remove the on-premises groups to avoid confusion and manage everything from Exchange Online.
Should you need more help on this, you can feel free to post back.
