I have synced some users with mobile phone information and found that all users can see each others mobile phone so I have change the attributes to be synced on both SourceAD and TargetWebService not to include telephonenumber. after that I have already done SourceAD-Full Import Full Sync / TargetWebService-Full Confirming Import / TargetWebService-Export and see all the previous synced users in the update operation logs
However, by querying users with Get-MsolUser command and see the information of all users with mobile phone information, the mobile phone still there and notice that the LastDirsyncTime of those users are still prior to the date I have update them to remove mobile phone information.
Now, it's 3 days past, I though the update process on cloud needs some interval, but now I'm not sure about my procedure or when those users will be updated. could anyone help me how can I make those users to eliminate their mobile phone information ?
PS. all users synced after I have excluded mobile phone has no mobile phone information on cloud as I wish.
