After the last update of Thunderbird the calendar will not hold the sync with Outlook calendar. I tried resetting the sync link without success.TB will flash the events from Outlook when I click the "Enable" button but not hold them. Is there a solution?

As Microsoft does not offer the standards based caldav on calendars on outlook.com I would be guessing you are using an add-on to enhance Thunderbird's capabilities. Perhaps that add-on needs to be updated for the new version you have installed.

Are you using the ESR 140 version or release 142? The author has stated that only ESR is supported.
