OnPremise archive mailbox not showing for Office 365 users
Just throwing another log on the fire - I am also experiencing this same issue. I have tried monkeying with some stuff like the archivestatus flag in the on-premises AD user attributes but to no avail. In my case, the cloud user can use (on-premises) OWA and access the on-premises user's mailbox and archive, but in Outlook, only the primary mailbox of the on-premises user is visible, even after manually adding the mailbox to the Exchange account in Outlook. I'm wondering if it's a limitation in Exchange Online. The way I see it, in order for this to work, it would have to look like the reverse of a cloud-hosted archive. In other words, I think the MailUser object in Exchange Online that represents the on-premises mailbox would have to have ArchiveDomain set to the on-premises mail domain, and possibly have the ArchiveState set to Remote, but unfortunately there seems to be no way to do this to the cloud MailUser (at least that I can find). Someone let me know if you find a way to do this!
Or, MS support, can we get a confirmation on the status of whether this is the expected behavior and/or when the feature will be enabled?
