The thing is O365 does not give us: `Microsoft.Office.Server.UserProfiles.UserProfileManager`.

It only gives us: `Microsoft.SharePoint.Client.UserProfiles.PeopleManager`

The only `remove` methods I got are:

1. **HardDeleteUserProfile**: which is only read only (value shows true/false). 
2. **RemoveSPUserInformation**: which I was not able to use.

Not sure if we are able to do such thing using PowerShell, contacting to Microsoft team for this. Will keep you guys posted if anything changes.

Cheers,
