evolution-ews has been removed from buster due to a vulerabilitly shortly before release. I see that a fixed version is available in testing[1] . Could it be rebuilt for buster and uploaded? Without evolution-ews, Evolution has no MS Exchange connectivity, which is what Evolution is supposedly about.
