[Users] vcalendar and davmail

[Claudius Laumanns]

Hi folks,

i want to use Claws's with MS Exchange, that is, vcalendar with
davmail. The URL should be like 

 https://clauman@gwdg.de:password:davmail.gwdg.de:1080/users/clauman%40gwdg.de/calendar

 or

 https://gwdg\clauman:password:davmail.gwdg.de:1080/users/clauman%40gwdg.de/calendar

i tried to percent encode charakters like @ \ : 
It did not work anyway. Claws always complained about a malformed URL
or a missing auth. Any Ideas?

Thank you for your attention.

Claudius
