Cannot move messages/write into folders?

[protobits]

I can't seem to save a draft, save a copy to Sent (but maybe this appears to be done automatically when sending) or move items to folders (for example, to drafts or trash). I get this message:

2018/04/08 14:47:10 cannot handle update event for message : cannot get message sequence number in All Mail: message not found in local database

You can only write into the Drafts folder.

I have a similar problem in that I can't read the contents of any folders except Inbox and move any mail from there. This means I also cannot archive any mail.

Thunderbird also reports 127.0.0.1 connection timed out, soon after trying to open any folders except Inbox.

Edit: Version 0.2.3 built from sources with the command in https://github.com/emersion/hydroxide/issues/54#issuecomment-488100149 with thunderbird 60.6.1

@emersion Is this a limitation of the Protonmail API? I get this message when I've deleted an email (thus moved to my Trash folder). Would be good to have this possibility. Now I have to remove any emails using the Protonmail Web UI or mobile app.

Or, is there another way to handle this?

Kind of. When sending a message, the ProtonMail API requires the client to create a draft message then send it (that'll implicitly copy it to Sent).

To copy and add new messages in arbitrary folders we'd need to use the import API. Some WIP code for this is in https://github.com/emersion/hydroxide/blob/master/protonmail/import.go.
