I setup a caldav connection to a SOGo email server, which worked well for about two days.
Now, it does not write the eM Client calendar entries to the Sogo calendar anymore. Any ideas about how to solve this?
The error is as follows below:
“MailClient.Accounts.ConnectionException: The character set provided in ContentType is invalid. Cannot read content as string using an invalid character set.”
here the complete protocol
(sorry, it’s in german…)
