Sorry, do you have some more information for us what your question is?

Veeam does only backup data but not the configuration or attributes of M365 objects. So regarding mail contacts, they’re not part of the backup.

If you have AD-synced contacts, you would have to work with your on-premises Active Directory in order to restore anything.

Qus is that while i am restoring mail via veeam backup for m365-

they are not restoring as it is they are before, we need to some manual process from outlook side for proper restoration.

sry mail contacts
