Office 365 Lync online Migration to Lync on Premise RRS feed

  • Question

  • We are using Office 365 (Lync and Exchange) and we currently have deployed Lync on premise and we'd like to migrate all our cloud users to premise Lync. 

    Is this possible and what's the best way to do it ? is there any specific tool ? or would DirSync do this once it's activated?

  • There is no tool to migrate users from a Lync online to a Lync on-premise domain. So, you will have to create users again in your Lync on-premise domain.

  • As I know there is no such method. Even in third party apps.
    E.g. check

  • Ok, I'd like to know in case I have created Identical users on active directory on premise. and deployed ADFS and Dirsync for Office 365 and Lync integration, would that affect the work of their Exchange mailboxes on cloud ? 

    I mean would there be any conflict on cloud cloud accounts? we basically used to work on office 365 and use exchange and lync and now we want to use on premise Lync.

  • We have Office 365 exchange and we have onprem Lync.  It works fine.  It's just that the client will prompt for the office 365 ID once in Lync and you have to specify in mobile client (different ID's).  But, you're saying that you have ADFS setup already?   This should be easy to test - you can manually config the Lync client to point to on-prem servers and test that way.  IMO.

    the client kinda connects the user to his mailbox using a similar process to how Outlook searches for the mailbox ... for us and AFAIK it works fine.
