Hi,
I also experienced that thunderbird behavior, I guess

When I move a message to Archive in Thunderbird. On the server the files
What exactly means move? Like drag and drop or via context menu "archive/archivieren"?
.Archives and .Archives.2018 are created (Thunderbird creates a subfolder in Archives)
How is this possible? On the server there is already an .Archive folder so it should create .Archive.2018 not?
I think this is intended. At least all my clients (thunderbird) do this. I think mozilla hoped to improve performance on big mailboxes by simply sorting archived mails by the mail's year.
Thunderbird uses yearly archived folders by default, but this behaviour can be changed.
