How to change domain from onmicrosoft.com to on-premise domain RRS feed

  • Question

  • From: @cpalacios9

    When setting up directory synchronization using Ad Azure Connect, is there a way to copy the users already created back to on-premise AD? If so, how do you change their domain from the onmicrosoft.com to the on-premise domain that was federated? I thought I could do it through the Office 365 portal, but I don't have the option to change the domain. I know users in the on-premise AD can be uploaded to Office 365 but I want to know if it can be the other way. Thanks for your help!

  • back to On-Perm? - No. AADConnect Sync is from On-perm to Azure

    You need to verify the custom domain in Azure. If it is managed, you need to convert it to Federated

  • Thank you.  This is my scenario:

    Had two users on Office 365 that still had their primary domain as trangodemo.onmicrosoft.com.  Can I convert these to use my federated domain?  And if I can, will DirSync create the user accounts in our on-premise AD?  If not, do all users have to have their primary domain as "domain.com" before running DirSync?

    Thanks,

  • Yes, you can. But you need first to delete both users from Office 365 and recycle bin. Then create though users on AD on premises and run dirsync. Then you will find those users synced on cloud.

  • Thank you!  So if we have 100 users on Office 365 and then we implemented AD FS, we would have to delete all of the users on Office 365 and re-create them on our on-premise AD so that they would then be copied over to Office 365?  We are planning to have a lot of users on Office 365 first before setting up AD FS and they will be using emails a lot so we don't want to have to delete users just to re-create them on-premise.  Any suggestions??

    Thanks!

    Greetings, Christian!

    I am afraid you're looking for User Writeback (in AAD Connect Preview 2):

    The feature desired is however unavailable in the GA build of AAD Connect tool. Refer to the features available now.

    But yes, you might want to vote for this feature and keep an eye on: Use AAD group membership to filter/control user writeback to ADDS.

    Thank you,

    In this case, you can talking about a hard matching. Yes. It can be done

    Verify the domain first, then enable directory sync. then hard match
