I saw this quote in this question:
MS support is poor, except when you've paid for a support contract... then its very very good. – gbjbaanb
This got me thinking. My company has had 2 support incidents with Microsoft a few months ago (before Stackoverflow was live). In both cases, we were pushing the limits of the SharePoint system we were building, and the API did not expose events to let us know when operations were completed. Both times, Microsoft's response was to tell us to add a Thread.Sleep() call and just wait for the operation to finish.
Now, I am all for the community working together to answer questions, but sometimes there just aren't answers to your question available online.
For the times when you can't find an answer, has paid support been worth it to you?
If you have had success with Microsoft paid support, please share what type of problem it was. I am trying to understand exactly what to expect from a support incident.
