--- Comment #6 from Garry Williams <gtwilli...@gmail.com> --- This bug went away for me. kontact-17.08.3-1.fc27.x86_64 may have fixed it. Two systems are now *not* complaining about "Cannot open". One uses gmail and the other uses davmail for Exchange. I think this bug should now be closed. -- You are receiving this mail because: You are watching all bug changes.
