How to revert back to mail from new outlook

damnwindows 

I was just testing out this new feature preview. But it was absolutely horrible. The default Mail for Windows used to hardly take a second to open. But this monstrousity takes a lot time to open. The supposed-to-be-user-friendly-ui is **bleep** so annoying and complex. And to add more touches of crap, there is no option to rollback to the old application.

Anyways, I tried several things and what seemed to be working for me was,

1. Uninstall the new Outlook 365 Pre application.

2. Open the Mail for Windows app (It will ask you to open microsoft store and install Outlook and select it as default app).

3. 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.

As of your old emails, if you have them logged in and if they're being shown in Email & Accounts settings. Then after rolling back to old application you'll be able to access them as always.

This worked for me, hope it works for you as well.
