Problem to access calendar through Davmail

jlnbdt

Hello,

I try to connect to my Exchange calendar (in read and write mode) through Caldav using Davmail.

It's a thing I've already done with Android and Thunderbird. But with Vivaldi, I get this error message:

Service CalDAV non trouvé : https://mydomain.tld:1080
(CalDAV service not found)

Server side, I get an error message which is related to SSL:

2022-08-10 12:58:36,124 ERROR [CaldavConnection-24362] davmail  - Received fatal alert: certificate_unknown

Don't really understand why I get this error message only with Vivaldi…

Thanks

@jlnbdt Thanks for reporting.

I just tested with DavMail Gateway running on my Windows desktop.

Used this base URL in vivaldi:
http://localhost:1080/users/[email protected]/calendar

Instructions here:
http://davmail.sourceforge.net/thunderbirdcalendarsetup.html

Was able to log in, and create events without problems.

Is this still an issue for you?
