Have you used Azure?

I've been using Proton for few years already and I did not have a single issue

(relevant context in another submission: https://news.ycombinator.com/item?id=48859976)

All services have outages. The difference is that when Outlook goes out (https://uptime.qodex.ai/outlook/incidents), it's a happy occasion because nobody can work and we all take an hour off, but when something like Proton goes offline, we're the only ones who can't access our important stuff.

Anyway, point is, Proton is generally very reliable, but shit happens.

I've had proton for years and have no complaints. I can only think of one or two other outages in that time. Most services do have outages from time to time. tbf, I don't seem to be having any issues with proton today, so far.

Proton is horrible. Notoriously bad email service.

I ended it after they only sent half my email to my accountant because they would apparently send the server saved draft version, which was not made current when I clicked send.

I have been a Proton user for the past 4 years.

No complaints so far.

What made you pick proton over something like mailbox.org? You'd get real calendar and contacts sync, IMAP and POP access, custom domains, and so on..

Proton seems really limited for what you get, and the webmail is absolutely abysmal in performance and design.

Depends...how large were your attachments?
