Q: Where can I find the logs?
The if the logs are enabled (In the OXtender preferences) there are two ways to find the logs. All informations are visible in the Thunderbird Error-Console and in the log file on disc.
On Windows XP (german):
C:\Dokumente und Einstellungen\%%USER_DIR%%\Anwendungsdaten\Thunderbird\Profiles\%%PROFILE_DIR%%\extensions\{E6050BDA-F130-11DD-8931-239656D89593}\oxcalendar.log
On Linux:
/home/%%USER%%/.thunderbird/profiles/%%PROFILE_DIR%%/extensions/{E6050BDA-F130-11DD-8931-239656D89593}\oxcalendar.log
