Mail is not syncing

[Markoise]

Steps to reproduce

1. Move mail to a subfolder in a mail client (Thunderbird, ...).
2. Alternatively, a mail can be moved to the junk folder in the mail client (Thunderbird, ...).

Expected behavior

Mail that is moved in another mail client should also be synchronized in the WebClient.

Actual behavior

However, if you use another mail client at the same time and move mails to a folder there, this will not be taken into account in the app. The e-mail is still in the inbox and must be deleted there manually.
If you want to open this mail, you will be informed that the mail cannot be found.
