Océane,
The process of adding a POP account for your department is a bit different in version 11.x. Please follow these steps to find the POP accounts:
- Log in as the System Admin.
- Go to Settings > Configuration > Email.
- Click on the POP tab.
- Edit the desired department by double clicking on the row or checking the box and choosing Edit in the content pane toolbar.
- Fill in the POP settings. For help on understanding the settings, please see the POP section of this help document. Though it is for version 10.x, the settings are very similar and the same definitions apply. In version 11.x, you'll see a new setting for "Who Can Start Email Tickets". Use this to choose the role that should be allotted to start tickets by email.
- Click Save.
Please let me know if this answers your question so the thread's status can be changed accordingly. Thanks!
