After Migration to new Server: No Answer Option to new Mail Tickets

  • Used Zammad version: 3.4
  • Used Zammad installation source: deb
  • Operating system: Ubuntu 18.04
  • Browser + version: Edge, Chromium, Firefox

I have migrated Zammad 3.4 to a new Server. I used the integrated Backup and Restore funktion.
Everything went finde, but there is a new behavior:

There are some Tickets that came per Mail before the migration, and some that are coming after migration, that I cant answer to. There is no “Answer” Button:

And in these Tickets, I cant create new Mails:


other Tickets are okay:


I did not get it yet, but it seems that the mail function only works in tickets, that did not come per Mail.

Check your group configuration.
I guess that the configuration didn’t change during restoration or you might have removed a mail channel which has caused this issue.

Sounds good. I will have an look.
Thank you for fast Response

This worked.
Wonder why only the main group had an empty Mail Adress after Migration.
But now it works, thank you.
