4. Open nextcloud calendar
5. The e-mail is shown, but without an attachment of the Event.

I'm not really able to follow your reproduction steps. What email are you talking about and how do you view it?

[georgehrke]

Closing because original reporter never answered to questions.

Hey, I have the same issue and I think I know what he meant.

He was talking about the invitation email from the Outlook calendar. He opens it in the nextcloud mail app an this mail is empty. You cannot click any button or any file which should be attached to the mail. Just an empty mail.

@stylefieber In that case please open an issue in the mail app repository
