This is likely to do with conflicting user attributes being sync'd to Azure (Office 365).

Have you by any change had an on-premises Lync or Skype for Business deployment?

I've come across this problem numerous times, and it's always been because the 'msRTCSIP-DeploymentLocator' attribute is already populated for the user. As a result, the user cannot be correctly provisioned for Skype for Business Online and never appears in the Online control panel.

Please check all the msRTCSIP-* attributes for your problem users - base on your other services working without issue, I'm fairly confident this will be the cause of your problem.

Kind regards

@Ben

Yes we have an on prem SfB deployment in the forest to which the user belong but those users haven't been provisioned for SfB. Nevertheless I will check all msRTCSIP attributes. Thanks for the advice.

Using the Skype for Business Online PowerShell module you can run:
Get-csonlineuser | ft interpretedusertype, displayname

Depending on the value of the interpretedusertype, this should tell you what the users' status is to consume SFBO.
