You can test with one user to change the msRTCSIP-DeploymentLocator from SRV: to sipfed.online.lync.com, wait for AAD Sync and check the Interpretedusertype. If this is ok for the user, clear the msRTCSIP-DeploymentLocator and check the Interpretedusertype after AAD Sync.

This is for all users:
Get-ADUser -Filter {UserPrincipalName -eq "UPN"} -Properties * | Set-ADUser -clear msRTCSIP-DeploymentLocator

Here is a good lin, how to remove the SfB onPrem correct with all steps

    Only password synchronisation was enabled and Attributes synchronisation was not enabled in AAD synchronisation configuration.
    I did following step :
    1. cleared msRTCSIP-DeploymentLocator attribute in local AD
    2. RECONFIGURED AAD with attribute enabled for lync server
    3. Initiatied manual synchronisation .
    Still the values remain same in online.
    In AAD synchronisation wizard , it shows success delta synchronisation and even I performed a full synchronisation but the values are not synchronising with online user.

      Hello, it could take a couple of days after you make changes to on-premises attributes to reflect Online,

       

      A couple of questions,

       

      What is the current state of all msRTCSip- attributes?

      Where are your DNS SRV records related to Skype/Teams pointing?

      What is the value of OnPremHostingProvider/HostingProvider (Online side)?

      What is the value of InterpretedUserType for the users?
