Using New Outlook on Windows for professional communication and productivity
I did some searching and found this:
- Uninstall the new Outlook 365 Pre application.
- Open the Mail for Windows app (It will ask you to open microsoft store and install Outlook and select it as default app).
- Ignore and cancel it. Again open the Mail for Windows app, keep repeating the same process again and again. After 3-4 tries, it'll open the old-yet-gold Mail for Windows.
It worked for me!
