messages should not come in threaded mode always,it shold be a separate feature.
Thank you for using Outlook Mobile and we really appreciate your support.
Recently, you requested that we add a setting to turn off conversation view in Outlook. Today, we are excited to announce that this has now been released.
To get this feature, just upgrade to the latest version of the app. You’ll then find the switch in the settings. Feel free to reach to us through the Help Section of the app if you encounter any trouble finding this feature.
The Outlook Mobile Team
