Hei, It's not a shared calendar and the error came up with all version down to 4.8.6. so I check the setup for the calendar in Thunderbird. I doulbe checked the instructions (http://davmail.sourceforge.net/thunderbirdcalendarsetup.html) and found that I had an alias of the email address in the position of " mail@company.com ". Deleting the old calendar setup and setting up a new calendar with the correct account name fixed the problem. Just weird that it worked before with alle the outher interactions...

Hi, I got the same error with verson 5.3.1. Any ideas? davmail.exchange.ews.EWSException: ErrorCalendarIsNotOrganizer User must be an organizer for CancelCalendarItem action. request: <soap:envelope xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages"><soap:header><t:requestserverversion version="Exchange2010_SP1"></t:requestserverversion></soap:header><soap:body><m:createitem...
