I don't know if it's possibile but I don't remember have seen it in OOTB.
I have an inbox called "My To Do List of Requests" which it's the english name.
And we have "Ma liste des tâches" which is roughtly the same but in french.
It's 2 different inbox which is bad.
I think we should have only one inbox but I never readed something about language translation on the same inbox.
Can I only keep the english one and just apply something for HPSM to do the translation to the french name?
Thank you if you can help me,
