I would suggest trying mailctl, it usually works: https://github.com/pdobsan/mailctl I have a bit written up on it for getting it working with O365: https://bence.ferdinandy.com/2023/07/20/email-in-the-terminal-a-complete-guide-to-the-unix-way-of-email/#oauth-mailctl Alternatively, if all else fails, davmail might be a solution, the aerc wiki has some stuff about setting it up: https://man.sr.ht/~rjarry/aerc/providers/microsoft.md Best, Bence -- +36305425054 bence.ferdinandy.com _______________________________________________ isync-devel mailing list isync-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/isync-devel
