Update for Windows Live Essentials Mail 2012 (KB3093594) kills WLM 2012

I will as soon as I am back to my pc at work. That will be in about 12 hours. Thank you for your time and efforts.

Yes, my calendar is intact at calendar.live.com, no change there. Where is outlook calendar preview?

If you don't see that heading (Outlook Calendar (Preview)) when you open your calendar online, your account has not yet been upgraded.

Since there should be no problem after applying KB3093594 to Windows Live Mail 2012 on Windows 7 with synchronizing the calendar for an account that hasn't been upgraded, I can only imagine that your repeated applications of the patch have managed to corrupt the local copy of the calendar. We can try to correct this:

1. Use the right-most button on the Home tab of the ribbon to Sign out of Windows Live Mail, then close the program down.
2. Copy the next black line into the start search box and press Enter:

%localappdata%\Microsoft\Windows Live Mail\Calendars

This should open an Explorer window at your Calendars folder. 3. Right-click on the folder named with the email address of your Microsoft Account (the one with the problem) and select Rename. Remove the '@' symbol from the folder name. 4. Launch Windows Live Mail and wait for any mail sync/download to finish. 5. Sign in and wait for the status message *Your calendar has been updated,*assuming it appears. 6. Switch to the calendar window (Ctrl-2).

Please tell us what happens ...

I am always signed in when I use windows live mail and my entries are always synchronized with calendar.live.com.  

Thank you. What happens if you follow the Sign out - Sign in routine I described?

I get  'Your calendar has been updated', but still no calendar entries.

What confidence have I got that if I install the KB in the magical "few weeks" I won't experience the disabling impact on WLM that others have reported in this forum thread?

Users whose Microsoft Email accounts are upgraded to Outlook Mail will no longer be able to synchronize mail, contacts and calendar using DeltaSync, because upgraded accounts are not provisioned for it.

With that one exception, there is no change.

Users of Windows Live Mail 2012 on Windows 7, 8 and 8.1 can install KB3093594 to enable upgraded accounts to synchronize mail, contacts and calendar using EAS instead of DeltaSync.

Users of Windows Live Mail 2012 on Windows 10 should not install KB3093594 until it has been updated to add full support for Windows 10, unless they never sign in with a Microsoft Account that has been upgraded to Outlook Mail.

There are hundreds of millions of Microsoft Email accounts to be upgraded to Outlook Mail. The process started in May 2015 and will continue for some weeks to come. Users can tell whether their account has been upgraded or not by signing in with it at mail.live.com:
