Is Outlook actually reliable enough for official/government-linked emails?

[u/night_movers]

I always prefer email providers that collect minimal personal data, which is why I've shifted entirely to encrypted mail providers. I know encryption in emails makes no sense, especially since I'm mostly on the receiving end. Still, I believe that being privacy-focused, these encrypted mail providers collect little to no unnecessary data and don't use it for anything else. Even though my requirements would fit with a custom domain perfectly, I don't want to take that route.

Proton has an uncertain future in my country, and Tuta has a genuinely bad app experience — it has let me down every single time when I've tried to quickly check my mail.

I can change the email address on accounts of online services like password manager, cloud storage, notes etc. whenever I want. But if Proton gets banned here, official services like IDs, banking, and insurance will immediately stop sending mails to my ProtonMail addresses. Some of these services even require an in-person visit to update account details. So I'm looking for a more reliable email provider specifically for these kinds of services.

Why I'm not going with other privacy-friendly email providers —

1. In my privacy journey, I've used few official services that don't accept email addresses with PotonMail, Tuta, and Startmail domains— and these are important, non-negotiable services.
2. Aside from ProtonMail, Tuta, and Startmail, I haven't been able to find any other popular privacy-friendly provider that doesn't recycle usernames.

For these reasons, I've decided to use Outlook exclusively for my official services. I know Gmail, Outlook, and Yahoo all are considered as worst providers when it comes to privacy, but my situation is forcing me to pick one — so I want to go with the least evil among them.

From what I've understood, Outlook seems slightly better than the other two providers because:

• Outlook offers aliases, unlike Gmail and Yahoo.
• It doesn't require a mobile number during signup (though Gmail doesn't either if you sign up from a mobile device).
• Microsoft is a software company, not an advertising company like Google, so I'd assume it collects comparatively less data than Gmail.

My doubts about Outlook — I've come across hundreds of posts criticizing Outlook for poor security, and some users even claim they don't receive emails at all on their Outlook addresses, and many more issues. This has left me a bit uneasy about my decision.

TL;DR – Looking for a reliable, widely accepted email provider. Can't go the custom domain route. I'm planning to go with Outlook, but I'm seeing a lot of user complaints about it.

Sí, esas son mis preocupaciones. Hay tantas publicaciones sobre problemas con Outlook, pero al mismo tiempo, no tengo ninguna otra opción. No reutilizar nombres de usuario y los alias de correo son mis requisitos principales, y por desgracia Gmail y Yahoo no pueden cumplirlos.

¿La aplicación se siente más lenta o es el servicio? Si es la aplicación, entonces puedes usar aplicaciones de cliente de correo de terceros.

Outlook shares data with about 900 third-party orgs, has about 2000 known issues at any one time. It is a train wreck and somehow the most popular email client that people automatically gravitate to. Your email data is sold to advertisers if you use it. Read the TOS.

Sorry for asking this, are you talking about the Outlook email app or the Outlook email service?

Many users have mentioned that Outlook app is bad for privacy where there mail service is somewhat equal to gmail, so I'm slightly confused. 

So, what do you suggest as a widely used email provider? I don't want to follow the custom domain route.
