Eingegangene Mails werden in den Favoriten (Ungelesene Mails) angezeigt, aber nicht im Posteingangsordner. Woran kann das liegen.
Incoming emails are displayed in Favorites (Unread Mail), but not in the Inbox folder. What could be the reason for this?
That usually means you have installed or upgraded to V10 and have chosen the default reccomended option to enable Inbox Categories.
However you can disable or customise categories as per the following support blog.
Ich habe keine Kategorien eingerichtet. Trotzdem besteht der Fehler. Aber warum?
If you have not enabled Inbox Categories and only seeing new mail in Unread under Favourites, then you could have setup a Local Rule to automatically move incoming emails to other account folder so then not showing in your Inbox or Inboxes.
So go to “Menu / Rules” and see if you have setup rules to automatically move emails. You can dblclick the rules to view them if there is any custom rules in there.
If there is no Local Rules setup “go online to your mailbox” and see if you have any rules or filters setup there to automatically move new mail to other folders.
