We encountered this same problem and after reading through this thread, I applied the suggested steps (including the additional steps of disabling tls) and yet the error still occurred. We just figured out that it is related to shared calendars. If shared calendars are enabled, the same error about an expired certificate occurs, but if the shared calendars are unchecked, the error goes away. Does anyone have an idea of where this could be originating? And hopefully, the 5.0.1 fix will catch this aspect as well. Thanks. |
