Infos:
- Used Zammad version: 6.3.1-1721805003.877871eb.noble
- Used Zammad installation type: package
- Operating system: Ubuntu 24.01 LTS
- Browser + version: Edge and Chrome
Expected behavior:
Just sending emails via smtp with M365 connector
Actual behavior:
We have a new installation of Zammad on a custom VM.
When we reply to a ticket by email, we very often receive the error “Unable to send email to ‘XXX@XXX.de’: can’t modify frozen String: “execution expired””.
We have connected our system to an M365 channel. Here the connectors are shown as error-free. The health check also shows no errors.
The issue is made more difficult because some emails are delivered correctly.
It is also only about outgoing emails. Incoming emails have worked perfectly so far.
We have already searched all forums (Zammad, GitHub, and others), unfortunately without success.
We have also checked the production.log:
Steps to reproduce the behavior:
Just answering a ticket per email.
Maybe someone could help us.
