  1. Does this affect login to their domain joined PC? Since it changes the user logon name, will that cause the user to lose access to their user profile on their PC, as windows will make a new one with the new name when the user next logs on?

    1. Hi Kyle,
      When you rename the user in Active Directory their SID does not change so when you logon to the computer with the new username, it associates with the SID of the previous user and everything the previous user had is now available to the new username exactly as it was before.
      Hope this answer your query. Thanks.

    1. Hi Kia, It all depends on how emails are set-up and where are they hosted, it can be just adding an alias for the new name and make them as primary address, so emails for both accounts gets delivered. Please let me know.

  2. I done this and everything is perfect except Skype. It seems their name on Skype for Business is still the old one and messages won’t deliver

  3. Hi Jatin,
    Read your explanation and was clear with the renaming conventions and its working principle in AD Users and Computers.However, i have a question can i rename the SID ID to the new User name so that everything will be changed.

    1. Hi Mahesh,

      Glad that the thread helped you, just quickly Do we know what are we trying to achieve so that it needs renaming of SID?

      Permissions and other uses of the account by Windows and Exchange shouldn’t be an issue, as they identify the account by its SID, not by its name.Thanks.
