Colours of Categories - shared email

Dear friends, can you please help with Colours of Categories - we use one email as a shared one - input of order. Two coleagues enter this email and work with them . Is it somehow possible to put there the colour of category so the other used can see the same as I see? It doesn’t work. 

Unfortunately it is not possible to do that Jana. I believe that the IceWarp client (re-branded eM Client) is able to sync settings with the server, but otherwise this is not possible.
