Great catch @Saurabh7019! Thanks for raising this issue. I suggest that we just remove this command from our code base since people should use outlook mail send instead.
Since this will be a breaking change, we'll have to remove it in our next major release.

Agreed with @milanholemans. Let's mark the command for deprecation already now, to give our users a heads-up, and then remove it in the next major version.

That is a fair point about deprecating it, let's create another issue to remove it in v11.

@Saurabh7019, are you willing to work on this issue? Let's add a warning for the users that this command will be removed in the next major and that people should use outlook mail send instead.

Sure, I will do that.
