I’ve added custom categories with custom colors, unpinned the categories pinned by default and pinned my custom categories. Theses settings only work for the current session. Wen I logoff and login again my custom categories settings are gone and the default categories are pinned again.
Bug: Categorie setting don't get saved
We are currently investigating an issue in Kopano Groupware Core related to categories that go missing after logout/login. Keep an eye on https://jira.kopano.io/browse/KC-1045.
