Hinfügen eines Emailkontos in K9

Ich kann meine Emailadresse [removed by moderator]@gmail.com nicht in K9 integrieren, während mit den anderen Emailadressen klappt es problemlos. Es kommt immer die Meldung, daß etwas falsch ist. Wie kann die Störung behoben werden?


What is the exact error message?

You didn’t include any information on what the error message was. My guess is that it was an authentication failure.

With gmail (and outlook/yahoo/…) if your client doesn’t support OAuth2 (as is the case with K9) you need to allow “less secure apps” and create/use an app-specific password (rather than the one you use for logging into your account). See: Less secure apps & your Google Account - Google Account Help for more details.
