When I accept an invitation, I get the message "Processing message failed. Status: 80040111." in Thunderbird. Further Thunderbird shows:

Status Code: 2147746065, The request cannot be processed.

Server Replied with 503

On the DavMail side I get a this in the log file:

This one is tricky: I guess you accept meeting from your inbox right ? If the meeting was changed by the sender in the mean time, you will get this error.

I also noticed we get a lot more errors in calendar since last Thunderbird updates. What I would try in this case:

• force calendar sync
• accept meeting from calendar instead of inbox
