Hi,

I am trying to add a new work account to my outlook/ authenticator and I get this error message:

"activation failed. Make sure that push notifications are enabled on the phone and your Activation Code is not wrong, expired or formerly used."

Notifications are enabled and it's the first time I am trying to connect so I have not used this code before. How can I solve this issue and finally connect to my new account?
