If I delete a Mail on iOS, it is not deleted in Thunderbird though. The iOS client only marks it as deleted instead of actually removing the data and Thunderbird does not understand the mark.

What does using thunderbird add for you?

I like having a native Desktop client and Thunderbird is a reasonably good one.

@copacetic
Check the settings in #Thunderbird. I think, it can deal with deletion markers. All clients have to agree on how to use a shared mailbox.

I looked into this again. I misremembered: iOS Mail does not "mark" deleted mails but is supposed to move deleted Mails on IMAP into a Trash folder (or Archive). That does not happen in my case and I have no clue why. The mail disappears in the app but is unchanged on the server.
