Can we enable Exchange Online Archive on Cloud for Hybrid Remote mailboxes

Hi, We have hybrid exchange enivornment set up. Where mailboxes are migrated from On premise. Accounts are synced from On premise AD to Azure. We are implementing Exchange Online Archive. Just wanted to know if there's anyway we can enable Online Archive for Migrated mailboxes from O365/Azure itself. Or do we need to enable it at on premise Exchange only? Enable-RemoteMailbox -identity xxxxx -Archive at on premise Exchange management shell?

It is synced from on-prem, you have to enable the archive on-prem as well and let that setting sync with this command:

 Enable-Mailbox -Identity ayla@contoso.com -RemoteArchive -ArchiveDomain "archive.contoso.com"

https://docs.microsoft.com/en-us/exchange/hybrid-deployment/create-cloud-based-archive

Otherwise, if you try to enable in 365 directly, you will see this:


The following error occurred during validation in agent 'Windows LiveId Agent': 'Can't enable the archive for
'<Mailbox>' because this user object is synchronized with the on-premises directory. To enable a cloud-based archive
mailbox for this user, you must use your on-premises Exchange admin center or Exchange Management Shell.'
