It would be very convenient to be able to attach documents directly to an event on Proton Calendar.
For example, a PDF for a meeting, so that it can be easily accessed.
This would also allow those invited to an event to retrieve the attached files. For example, tickets for a concert.

how it should work:
1. get an e-mail with info
2. create calender event, attach info from e-mail
3. in times of ai: autofill event

Thousands of essential use cases already named here. Definitely needed!

This has obvious work applications, but I constantly use my calendar to store PDF tickets for events and related. It is the custom of me and my friends - very necessary, in my opinion.

This is the only feature preventing me from using Proton for my work.

So many friends send images or pdfs with event info and I can't just copy and paste the details of the event. I have to transcribe it without this feature.

I see this is missing, and am that much closer to going back to gcal. I pay, btw

This is incredibly useful. For example, one obvious use case is including the ticket(s) to events directly in the event. Another option could be linking an event to an email from the inbox.

It's incredible Drive and Calendar are not integrated and the idea was reported in 2021. This shows how Proton works as a company. New products at all costs, no love for the basics.

Seconding this. Use-cases I had in mind are as follows.

I often sort out tasks I have to, or want to take in the future. I then create a calendar-item as a reminder to ensure I actually sort them out.
Would be great to link to a Proton Drive document either pre-existing, or create a new one for this calendar-item.

Note-taking during meetings is also a great example. Link a default document to the calendar-item and easily look up notes of past meetings, or write new ones for the current meeting. I don't do this currently due to the lack of integration, but in the past I've used Proton drive documents to write down notes of a meeting.

I really dont get how this isnt a thing already. really makes it difficult with train/event tickets

Being able to attach things such as pdf's of tickets to the calendar is for me critical and I won't be using it until it has this facility.

That would be really helpful! Even just linking an email received or an attachment from Proton Drive would be useful.

This missing functionality is one of those which makes Proton suite unusable in a professional environment, esp. as a secured emergency communication system (in case of cyber crisis). I highly regret the absence of basic/core functionalities such as this one, aside useless bells and whistles.

I'm taking my wife to the theatre next month, so I created an event with all the details — address, time, etc. I would have loved to be able to add the theatre tickets as an attachment, since they are often PDF files with QR codes or barcodes.

A simple thing as saving tickets to a concert in the calendar and they pop up when you need them.

This is in the wrong thread.

It would be extremely helpful to have the ability to attach files directly from Proton Drive to events within Proton Calendar. For example, when scheduling a job interview or meeting, I should be able to link relevant documents, such as my resume or cover letter, directly from Proton Drive.

How it would work:

- Users can attach files directly from their Proton Drive to calendar events.

- Files remain stored in Proton Drive, with no need to upload or manage them separately within the calendar.

- The attached file would appear as a link within the event details, making it easy to access relevant documents for the event.

Totally agree that this functionality needs to be added.

Workaround for now:
Upload a file to Proton Drive, create a link and paste it into the calendar entry. PDF and JPG tested and is opened in a browser upon click on the link, no login required.

Great idea and the closest existing I have identified so far for a better integration :

In a Calendar event, I would like to attach (or link to) a photo or a document (in the Drive / Docs), relevant to the event. I'd like to have some minimal formatting options in the description too. That will make for a better integration and a great time-saver.
Also, it would be awesome to have some sort of a visual index / identifier for the events ! Imagine a small logo, a thumbnail photo or document preview shown as part of a/the quick summary look-up when hovering over an event.
