Is there a new way to refresh the backend User Database foe Skype For Business when its part of Office365? Update-CsUserDatabase does not exist for me.

Hybrid Exchange 2010 with Exchange On-Line/Office 365.
AD Cloud Sync with on-Prem AD Server.
Skype For Business as Part Of Office 365 Premium

Years ago I tried installing a Lync Server, though never got all the way though. My Exchange User had a SIP email address entry in it.  This was Causing my Outlook to complain that My SIP and SMTP Addresses were not the same.   No One else in the Organization had a SIP email entry so I just removed mine. After that I could no longer login to Skype For Business. Did the Delete of the Appropriate files on my Machine, cleared the Stored Credentials, waited 24 hours and I still cannot login to Skype on ANY Machine (Mac/PC/PC) I can login to Exchange OWA, office Portal, Sharepoint, etc. Just not Skype. I seem to be the only affected user, other users are not affected.

Reading though many google searches I came across Update-CsUserDatabase which is supposed to Pull a copy of the User's Attributes from AD, though when I go to run that Command I get: "Update-CsUserDatabase' is not recognized as the name of a cmdlet"
Though I can execute other get-Cs Commands with no issues, so I know I have a Good connection to the back end SfB.   (See Below) I can cycle though other Update-Cs Commands, just not the Update-CsUserDatabase one.

Is there a new way to refresh the backend User Database foe Skype For Business when its part of Office365?
