Using classic Outlook for Windows in business environments
Just adding my voice to the chorus. I have been using the basic, but very functional, Windows Mail app to manage my four email addresses and the unified inbox is the primary reason for this.
If MS retires the Mail app and forces everyone onto the new Outlook app without a unified inbox functionality I will finding an alternative client.
Unfortunately I have tried most of the other email apps and find them all excessively busy for my needs.
Please just add the ability to have a unified inbox for the Outlook One app. Please. 🙏
