Exchange 2010 Extend Schema - Now I Can't Copy Users


  • Hi,

    I have an odd issue.

    We ran through a staged migration from Exchange 2003 to Office365 which seemed to be successful.

    I then went ahead and decommissioned our Exchange 2003 mail server only to find I could no longer manage proxy addresses through ADUC I have to use adsiedit (OUCH) however I could copy user accounts when creating new users.

    I was advised by MS that if I were to upgrade my schema to Exchange 2010 I would then have the ability to manage proxy addresses without using ADSI however that was not the case without an actual on premise exchange server.

    Anyways so I'm now left with an extended schema and now I cannot copy user accounts. I get the following error:

    "Windows cannot create the object <User> because the name reference is invalid"

    How do I get this ability back?

    Uninstalling exchange will not remove the schema as I'm sure you know and I dont think hacking up AD with Adsi is supported so how do I get out of this mess'?
