Zammad only supports SMTP or sendmail as notification channels.  
Right now you cannot use Gmail or Microsoft 365 without workarounds…

There’s already a feature request for that, give it your heart on the first thread to vote.

> Hi, Since Microsoft and Google disable the basic authentication for SMTP, we cannot anymore use the Email channel to allow Zammad to send notification. It would be nice if we can have in the drop box “Mails send via” of the Notification by Email dialog box the ability to select account setup like Microsoft 365 or Google. Thanks for this awesome tool !
