We are set up in a hybrid configuration with O365 and our on-premise Ex2010 server. I have tested a remote move request with one mailbox and it worked fine going to O365 and back to on premise. The mailbox and archive both moved in this process.
I would like to migrate my users mailboxes to O365 but keep their archive mailboxes on-premise. However, the move mailbox only option in remote move request is greyed out.
I have the user mailboxes in one database and the archive mailboxes in another. Why cant i move just the mailbox and keep the archive on-premise? Am i missing a setting?
Hi rreidAD,
For organizations that have a hybrid deployment, a limited set of scenarios is supported to create archive mailboxes. These scenarios are as follows:
Primary cloud-based mailbox with a cloud-based archive mailbox
Primary on-premises mailbox with a cloud-based archive mailbox
Primary on-premises mailbox with an on-premises archive mailbox

I think that i may have found my answer. The archive mailboxes actually are residing in the same database as the user mailbox. None of the archive mailboxes ever got created in the archive database. I am executing a local move of the archive to the archive database and then will attempt to move just the user mailbox to O365.
No dice, i found another user who had their archive in the archive database already. When i tried to move just he user mailbox, the option was still greyed out. Can i have the user mailbox in O365 with the archive mailbox On Premise?
Hi RreidAD,
Please refer to the following site for more information about how to enabling on-premises archive.

Also please make sure that you have been assigned with permission to perform this procedure. Hope this can help. Thanks.
Hi,
It seems that we cannot keep the archive mailbox on-premise if the mailbox has been moved to O365
any update?
Well, it looks like we can't have an on premise archive for a cloud mailbox. Which, frankly, stinks. I would like to set archival backups of the mailbox archives via our on site exchange server (which is already in our regular backup cycle). But without on-premise archive, that is not possible. Maybe i should put in a feature request on this.
Is this information useful for you?
Useful in that i now know that we cannot do what we want to do. Having archives on premise would be a less expensive option for us. Several of our project managers have large archive mailboxes since they need to pull up info on past projects quickly. Most of our projects take several years to build, so the mailboxes get pretty large. Having them move mail to archives is one way that we try to keep mailbox size down. I have 5 users whose combined mailbox/archive mailbox are over the 25GB limit for moving to the cloud. The price increase to move to an E3 plan (to get the 'unlimited' archive storage) is cost prohibitive for us at this time since it is over twice as much as we are paying now
