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

GoodResource 311 Reputation points

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 -RemoteArchive -ArchiveDomain ""  

    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.'

    @Andy David - MVP Hi, I was just trying to test and i could see i was able to delete exchange online archive and create it from new Exchange Admin portal. But if i try to do it traditional way that is "Enable-Mailbox xxxxx -archive" i am getting the same error. But i can provision or deprovision from new exchange admin control panel for synced users from local ad. This is inconsistent behavior. Any idea if anybody finds this behavior?
