Because of a problem exporting v12 Azure SQL databases I had to copy my existing database, drop the old one copy the copy again to get the old database name again.
And now the new problem begins: Azure tries to create a backup for the old and non-existing database and sends me hundrets of error emails. As far as I can see there is no way to cancel the errant export through Azure web interface or power shell.
The error message sent by mail is:
Automated SQL Export failed for : at 13.03.2015 14:23:13. The temporary database copy was made, but this copy could not be exported to the .bacpac file.
There was a issue like that before but regarding to this Post it should be fixed.
