I can confirm this: Ubuntu 14.04, Evolution 3.10.4. with EWS Exchange account.
Evolution asks for password after start, then I cand fetch emails, but after few minutes it asks again and claims password is wrong - which is untrue - i made sure of it. At the same time Evolution's entry disappears from gnome keyring. I tried to recreate Exchange account, but it didn't help.
