In response to this report of problems that my colleague Corby Kummer encountered when installing the Outlook-indexing program Xobni, the CEO of Xobni, Jeff Bonforte, sent me a note. I post it here with his permission.

Thank you for your posts about Xobni. We were disappointed to read about Corby Kummer's bad experience with our product. We take performance and stability of our software very seriously and have spent over 5 months working out bugs and optimizing speed prior to releasing the product from beta. After 2M+ downloads, we are unaware of any user that has experienced Corby's issue.

We have reached out to Corby directly, but in the meantime we have begun researching the issue. At this point we don't believe that Xobni itself caused his issue. Instead, we believe when he installed Xobni (any software in this case), it triggered a rare Windows bug or registry corruption. Of course, we don't rule out the issue is with Xobni, but it seems likely it is a Windows bug similar to this Window's RSL (registry size limit) issue (

Regardless, it is a bad issue, and even if Xobni is uninstalled, we want to make sure it is fully resolved. We will coordinate with Microsoft support. Though Corby had a bad experience, I hope you will give the new Xobni a try, like thousands of new users each day.

You are welcome to reach out to us, even on Twitter (@Xobni), to tell us about your experiences. We have had incredibly positive feedback so far like that from your colleague Barry Simon. If any of your readers encounter a dramatic issue, please feel free to have them contact Xobni support or me directly.

Thanks again,
Jeff Bonforte

PS: You can also tell Barry we are working on some more advanced search options that should please him.

While waiting for Corby and the Xobni people to get to the bottom of this issue, I have to say that the prompt, helpful, and, in the circumstances, very good natured response by a CEO is impressive. (And is the opposite of the blustering defensiveness I often marvel at in China.) When I'm able to download the program, I'll know more about how it works for me.
