Unable to create an exchange account after update

Hi
Thanks. I cannot fix this problem and I spent 2 months without calendar on my FP. It becomes tricky.

  • my old exchange account was linked to my professional account based on OBM. One told me that OBM cannot support DAVx5, ICS…
  • i tried with my personnal provider (Free, I’m in France)… and i didn’t success. Thanks for your help: i would like to avoid a paper calendar.
