Hi KCA,
answering to you both, KCA AND wst459 below:
- yes - you must have hit it by accident. It usually only asks and if you don't like it you can switch back. It is no problem to switch back. Annoying though are the constant offers and the stupid toggle.
- if for some reason there is no more toggle to switch back, uninstall everything Outlook and re-install the Mail app from the app store (or try Repair ..?)
- from what I researched Windows Mail app is going to be working till end of 2024 (not 100% sure about the time span) beyond that, you can always keep it or re-download it from the App Store and continue using it, as I found out, similarly, to Movie Maker / still working nicely / downloadable, even after discontinued years ago.
- another option, if all fails, are various simple mail apps you find on the app store, most of them free and very similar to the Mail app.
So, at this point I completely ignore everything "Outlook" and keep using Mail app. as long as regularly installed / working. Unfortunately there is no way of getting rid of the toggle (in the Mail app). However, there are many articles about how to get rid of it in Outlook, if someone uses the regular Outlook app.
BTW - as seen in a previous post, some seem to confuse the Windows Mail app with a view / option in the Outlook app, desktop or
Outlook 365. Here, we are talking about the stand-alone, simple, Windows Mail app that comes with Win10 and 11, free, ad-free ... and has nothing to do with Outlook. I have everything deleted/uninstalled with the name Outlook to it. The Windows Mail app handles everything as good, if not better, faster, is more logical, simpler. Outlook, regardless if desktop app, 365 or New Outlook is all completely unnecessary and over-constructed, let alone full of ads (unless you pay for an ad-free version.)
Anyways - hope this helps
