I can confirm the issue. Even if the problem is fixed with a cast, the iCloud mail bodies were still not displayed:

Yes, somehow issues with icloud occur from time to time, yet I don't know why. https://github.com/nextcloud/mail/issues?q=is%3Aissue+icloud+is%3Aclosed

Right now we do not have any account we could test/verify this bug with.

[BenS89]

@ChristophWurst Since iCloud is one of the most used mail providers, it would be great if the issue could be solved.

An iCloud mail account can be created without any cost the same way like using Gmail, GMX or Web.de: https://support.apple.com/de-de/HT204316#web

Believe it or not, but we've heard the same reasoning for pretty much every bug. There is always a person to whom a particular bug is the most important one to fix.

We'll look into it when time allows or if a customer runs into the issue. Until then, I would be very grateful for debugging help. I can give you pointers and everything on how to get started.

Hello,
finally someone found how to resolve the bug ?
Thank you for your help !

[ChristophWurst]

nope, we're lacking the resources to check such specific setup. if you want to help move this forward dive into this yourself if you're a developer, ask a friend or hire someone who can help :)

Nextcloud is so complex but it’s so wonderful ! I think it’s the better soft I ever seen so I can wait !

I have this issue as well, what’s confusing is it is able to show the number of emails in a particular folder, but shows all folders as empty when selected.

[ChristophWurst]

The number in the sidebar is a direct query to the STATUS of the IMAP mailbox. The contents displayed go through a caching layer. That explains the difference.

[funkthew0rld]

Thanks for clearing that up for me. If I knew how to code, I would for sure help out with the nextcloud project. You guys do great work.

[ChristophWurst]

No problem. Appreciate good bug reports just as much :)

And on a side note we're not just guys :wink:

Hi,
I have the same problem, I use nextcloud (which I love) within a docker environment, latest nextcloud:apache image in a docker swarm stack.

It is just for personal use, so is do not mind if I have to break things in order to provide useful log/debug ..
How can I help? Is there any log that you may need, or debug statement I can put in the nextcloud src code? I May I be your guinea pig, but I need some guidance as I am not that great coding in PHP.
