Original GitHub issue: https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/76

Self signed certificates are not acceptet? Is there a workaround?
I ve got this error:

"An error accurred while sending the request.
Die zugrunde liegende Verbindung wurde geschlossen: Für den geschützten SSL/TLS-Kanal konnte keine Vertrauensstellung hergestellt werden..
Das Remotezertifikate ist laut Validierungsverfahren ungültig."

Outlook in MS-Office 2010 under Windows 10 with owncloud. The same adress works fine in thunderbird lightning, but have to use Windows and Outlook...

Thanks for your support!

please read instructions in the readme file. either import your certificate in the trusted machine store or disable certificate validation in the app.config
