On-prem mailbox with Online archives

Can anyone let me know what type of user the Exchange Online user is when the users primary mailbox is on-prem (Exchange 2010) and the archive is located in Exchange Online?

At the moment we have some issues with messages not being archived, and we have some users who are mailbox users in Exchange Online, and some users who are mail contacts in Exchange Online. I would have thought that if you have an Exchange Online archive configured, then the user type would need to be a mailbox user rather than a mail contact in Exchange Online

  • If you are in a hybrid configuration, you can assign Exchange Online Plan 2 or Exchange Online Archiving to enabling archiving features. You can assign licenses for on-premises mailboxes as well, no (online) mailbox will be created additionally. This was the case a long time ago ...

    To answer your question about the recipient type in Exchange Online: it is a mail user with archive enabled. You can check it with Get-MailUser <cloud mail user> | FL *archive*

      Yes there is a hybrid setup in place. I have read that technet article, but it doesn't explain what user type the Exchange Online user is when the primary mailbox is on-premises and the archive is in Exchange Online.

      • Do you actually have "Exchange Online Archiving" licenses though? Or just the usual Exchange Online / Office 365 E3/E5 licenses?
