Notification "User already exist", but user cannot be found

  • Zammad version 5.2.x
  • Used Zammad installation type: package
  • Operating system: Ubuntu 18.04
  • Browser + version: Firefox 113.0.2 (64 bit)

Expected behavior:

I try to add a user, but when I click submit I receive an error:

When I search the users emailaddress I can see the person is cc’ed in multiple tickets but there’s no user:

Since I’m unable to find the apparently already created user with this emailaddress, I’m stuck in a loophole.

How can I find the user that already should exist

You could use the API to list the info from whatever user has the email address, by using a URL like this one in your browser:

That being said, does the user show up when you search for their email in the users section of the admin settings?

Thanks for your reply.
I tried the API:

Also tried to locate the user via admin settings:

No results unfortunately

Try changing the word email to login in the API query.

Thanks for the addition. Unfortunately same result (as in no result)
