Comment 10 for bug 711678

I reinstalled 0.12 and ran the test.
Thunderbird does not show the double entry upon refresh or restart.

Creation of concurrent events:
When I create a concurrent event, another 2 more entries appear in my outlook calendar.
Resulting in a total of 4 events reflected in outlook.
But Thunderbird only shows 2 events, even upon restart

Just for visualization
What I see in Thunderbird:
              |-------------|------------|
5:00 pm | Event 1 | Event 2 |
6:00 pm |-------------|------------|

What I see in Outlook:
              |-------------|------------|-------------|------------|
5:00 pm | Event 1 | Event 1 | Event 2 | Event 2 |
6:00 pm |-------------|------------|-------------|------------|
