Hello.
I set up a email box to send and receive emails. It works fine.
The issue is that new ticket created from incoming email is not shown in the ticket list.
In the email box I see that email has been fetched. On dashboard I see increased tickets number of my department.
I have admin privileges.

osTicket Version v1.11 (d4e240b)
Web Server Software Apache/2.4.29 (Ubuntu)
MySQL Version 5.7.25
PHP Version 7.2.10-0ubuntu0.18.04.1

Admin panel -> Settings -> System.

What is the default department?
Does your account have access to said department?

    Admin panel -> Agents -> Agents -> Your account:
    Permission tab
    Miscellaneous tab
    is stats checked?

      Then it sounds like you do not have access to the department that the ticket is assigned to.

        But I have access to tickets from this department, which were created via osTicket interface.
        It is on the first screenshot.

          How many departments do you have in your instance? Grant your account access to all of them and see if the missing tickets show up.

            I have only two default departments Support and Maintenance. And I have full access to them.

              Can you look at your ost_ticket table and see what the assigned dept_id or team_id is? Because the only time I have ever seen anything like this is when someone does not have access to the dept or team that they tickets are assigned to.

              Status 0? There is no status 0.

              Whats your Admin panel -> Settings -> Tickets -> Default Status set to?

                I suppose that's the problem. I've updated status of a ticket via sql request.
                And now it is shown in ticket list.

                Andrey changed the title to Tickets created from email have status = 0.

                I've asked the devs to take a look at this thread.
