Waving to Lowway. Yep. Me too, as per my thread which you found. It would be nice if this was fixed.

G’Day Lowway, No, I didn’t get a response or solution to the problem when I create or edit a Calendar event on Android, and it won’t sync back to Telstra and hence to my PC. I am still getting error messages from DAVdroid on my Android phone. As I create most Calendar events on my PC it hasn’t been a great problem, but I do want it fixed. However I seem to have asked too many questions in one thread, so this one hasn’t been looked at. Bitfire marked the thread as Solved, not me. I was going to start a new thread just on this specific issue but haven’t had a chance to get back to it. Frankly, with the extra work required to support a Telstra based Email, Contacts, and Calendar system, which doesn’t support Tasks anyway, I am thinking of moving away from the Telstra Email, and using either Outlook.com or Google Gmail, both of which can support full synchronisation with Outlook 2010 on my PC ( I think). But I have to work through some issues before doing that. Contacts syncing is working fine now. Note that there have been quite a few updates to DAVdroid on my phone, so I assume the fix for Contacts has been incorporated into the main program updates. PS: I just read your thread, and I see they know what the problem is. I also suspect that there is no point trying to get Telstra to fix the issue at their end, as they likely wouldn’t do anything. This would affect all Telstra customers, of which there are many using the Telstra Email. I also see that rfc2822 has commented on the GitHub thread just 3 hours ago, probably due to your thread. So maybe a fix will be forthcoming. I hope so.
