D. S. (ID: 000000a0fa990de8) Voted 4 ★ - Updated 08/02/2024 EDIT-2: 4 Sterne - Beim gmail-Postfach verschwindet die rote Zahl für 1 ungelesene Email nicht, obwohl die Mail gelesen oder im Mail-Check gelöscht wurde. Auch Aktualisieren ändert das nicht. Hilft nur Browser schließen und wieder öffnen. EDIT-1: Nach anfänglichen Schwierigkeiten habe ich nun keine Probleme mehr mit der Erweiterung, klappt alles, wie es soll. (5 Sterne) 1 Verbesserungsvorschlag: Ich fände es gut, wenn man im MailCheck die Auswahl für SPAM hätte (neben dem Mülleimer).

edge edge (ID: 0000004684f3faa1) Voted 3 ★ - Updated 09/27/2022 EdgeブラウザでOutlookメールをこの拡張機能上で利用していますがブラウザのクッキーを削除するとログインしたままに出来なくなります。 再起動するたびにログイン催促画面(https://outlook.live.com/owa/)が表示されます。 ここからログインしても再起動するとまたログアウトしてしまいます。 解決策ですが上記のページからではなくマイクロソフトアカウント(https://account.microsoft.com/)などのページに移動して一旦ログアウトしてから再度ログインすると、この拡張機能にもログインしたままに出来ます。 あと要望ですが英語に対応してほしいです。

(ID: 00000020ce71e6a4) Voted 1 ★ - Updated 08/09/2022 Seit dem 08.08.2022 überfällt Edge mein Mailcheck und verhindert den Zugang über Google (Standartbrowser). Auch eine neue Registrierung Mailcheck landet immer bei Edge.

Marco Stockbauer (ID: 0000004d04cf06c0) Voted 1 ★ - Updated 07/26/2022 Die Erweiterung ist genauso schlecht wie eure Internetseite. Man kann sich nicht einloggen, kriegt ständig Fehler und 40 Minuten muss man warten, um überhaupt ein Fenster angezeigt zu bekommen. Aufgrund ständiger Fehler, extrem lange Ladezeiten, plötzlichem Rauswurf aus "Sicherheitsgründen", obwohl ich beim Verfassen einer E-Mail war und einfach Abstürzen, wende ich mich von web.de ab. Ihr habt mir so viel Ärger gemacht, dass ich fast meinen Verstand verloren habe. Irgendwas habt ihr die letzten Wochen so dermaßen verschissen im Serverbereich, dass euer Service nicht mehr verwendbar ist. Eigentlich sollte ich euch anzeigen, für die psychologischen Schäden, die das Programm verursacht hat. Unglaublich, wie ihr noch auf dem Markt sein könnt.
