Sending notification/system emails not possible


  • Used Zammad version: 5.3.1
  • Used Zammad installation type: package
  • Operating system: Ubuntu 20.04
  • Browser + version: MS Edge 109.0.1518.61

Expected behavior:

  • Send Notification/System emails via MS365

Actual behavior:

  • Notification/System emails aren’t sent

Steps to reproduce the behavior:

Emails from ticket are sent normally. However, the notification/system emails are not sent, such as: Password reset.
Emails import is also running fine.

I hope you can help me

Thank you :slight_smile:

In order to send using Microsoft 365, you’ll need to add it to your outbound and Notification configuration. Sendmail will not work.

Microsoft has changed the authetification to a new standard as of 1/1/2023. When I enter my login data there, I get the following error:

in October 2022, they no longer allowed basic authentication. You will need to use the Microsoft 365 Channel instead of email.

I use the Microsoft 365 Channel. But all system notification don’t send with this methode.

The email import is working fine, also sending emails from tickets.

Change this to the same support email.


It’s the same support email:

It’s also not working

Microsoft has pretty harsh rate limits regarding their E-Mail-Accounts and thus is not advisable to use for system notification emails.

You can easily lock your whole tenant if you are using it for stuff like that.

We don’t have that kind of volume, so we are good.
