Hello Khushi kumari,
Thank you for posting in Q&A forum.
When migrating groups, ADMT focuses primarily on the group's membership and permissions, and does not involve the group email. Group email is typically not a standard attribute in Active Directory and therefore won't be migrated.
You can try group email migration via the following link:Use PowerShell to perform a cutover migration to Microsoft 365 - Microsoft 365 Enterprise | Microsoft Learn,Batch migrate Exchange Server public folders to Microsoft 365 or Office 365 | Microsoft Learn
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
Yanhong Liu
