For several years I have been sharing my Windows Live calendar with my wife, my phone and my tablet via Calendar.Live.  In the last week or so calendar changes made in Windows Live Mail 2012 have not been propagated/synced.  Looking at Calendar.Live it appears that calendar updates from WLM are not being synced with it.

I have tried the following:

1. Renaming the Windows Live Mail > Calendars ><my mail address> folder, rebooting and restarting did not work.  Calendar showed as empty even after a long wait. 

2. Repaired Windows Live essentials.  No change.

3. I have added some events to Calendar.Live but these do not get propagated to WLM or to my phone or tablet.

4. Also the calendar app on Windows 10 shows the earlier version of my calendar.live calendar before the new events were added (just like the phone etc).

Version of WLM is Version 2012 (Build 16.4.3528.0331)

Any suggestions how to get all my calendars synced again?
