Hi @Mukesh Bisht ,
Like what you've mentioned, it is true that the Outlook webmail has different functionalities that Outlook desktop email client may not have and vice versa. Your preference for which platform you will use still depends on how you proceed in your daily activities.
Currently if you really need the webmail feature, you can install the web version of Outlook—either Outlook on the web or Outlook.com—as a progressive web app.
What that means is the web browser is offering to turn the Outlook Web service into a stand-alone "app" that you can launch without first having to launch the browser and navigating to the Outlook online site.
Besides, many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future, you can make a suggestion via this link.
