Thanks Rob! So the "can not sync" message would not be something the user is supposed to "try again"? I am just confused what the UX guidelines are for such errors/warnings. And is there only 1 solution allowed or would be something like "Mail cannot sync
at the moment [Retry] [Change Account settings]" be possible too?
Of course if there is no internet connection the error could just simply say "Mail cannot sync at the moment. No Internet connection. Will retry if Internet connection is established again".
