Very important to have this option on mobile devices. The bridging on the desktop is not enough as we cannot carry our laptops with us everywhere, and additionally I prefer the protonmail client app instead of other third party ones.

This is very important, and even though there is the bridging software on a desktop to make emails accessible via another mail client such as Outlook, it is not feasible to carry your laptop everywhere you go, and if you travel quite a bit you do need access to your emails offline at all times.
After all, other email service providers are able to do this.
I also like the protonmail client app, and would rather use this instead of going back to other third party apps.

Creating offline calendar entries on mobile is a must-have for me. It is quite annoying trying to create an entry and waiting forever because the connection is slow or even broken.

This is for me one of the main reason for not doing a full switch to Proton.
It's really a must-have feature for the mobile apps...

It would be great to be able to access read emails with the mobile app.
I have been already in situations, e.g. traveling to a different country, in which I was not able to access important information that I had in my protonmail account.

Do you think it would be feasible implementing this feature in the mobile app?

Would really like the option to access some emails (if not all) on my iPad offline. This is critical for my continued use of this app.

I'm surprised that you can't even edit and save a calendar event without being online. Any old PWA can do offline then synch, let alone a proper Android and Apple native app. Craziness. This needs to be implemented asap.

Same here. On Gmail (which I'm currently migrating away from, if I don't have network, or the network is slow, I'm still able to view emails, especially if i need to check emails for references or information I need). I'm unable to do this with Proton, sometimes even the folders don't load.

Adding my voice here too. Sometimes the network is down and I need to access a boarding pass in my emails.

+3. This situation has already caught me off guard multiple times where I suddenly needed access to an important email and the poor network really screwed me over.

Please review this request again!

Is offline mode on the roadmap? Or at least caching already opened emails? Thanks

It is May 2022 and still no offline mode for IOS? Protonmail privacy is of no use to me when i cannot access my own emails offline. I gave it a try, paid subscription and patiently waited for years. Time (and a patience) is running out though. Offline access should not be a special feature in a year 2022 but a standard part of service and it is a dealbreaker for me.

AFAICT - ProtonMail is an "abandoned" service, at least, as far as the mobile apps go: they haven't been renewed in years, they are tired, dated, barely usable apps, belonging to 10 years ago.

The fact that they lack even the most basic functionality that even the most threadbare mobile client apps provide for granted (threading in folders; offline access) shows that, as far as Proton management is concerned, we, the users, are taken for granted too.

5 years later when request was created it still not implemented.

This should be in the mobile apps, at the very least

Recently stumbled on this.. How is it possible that this feature is not there? Seems as one of the basics. Insane.. Just add something as simple caching of all mails below configurable size X until cache filled. Then just delete oldest to cache latest.

Offline needed for when Internet unavailable

How about an offline mode for the android app where one can read ones mails (from the last synchronizing).

It might be possible to make an option where the user can decide for example that he wants to store the mails of the last week on each sync (to be able to read them without an internet connection). As the encryption takes place on the device, these mails might be stored encrypted on the device.

Same. I have occasionaly a weak internet connection, work in trains, hotels etc. Still need to be able to see my older emails.
