Object reference not set to an instance of an object.

Sometimes I get event 0 from Office often (usually in pairs) during the day. The open Office app is Outlook mostly, but there are times with Word and/or Excel running. I have not been able to tie the log posts to some action on my part. and I am at a loss on how to proceed.

I have not made modifications other than using some 3rd party add-ons for Outlook. I expect that one of them is not playing nice. The information in this event logging is minimal. There are no relevant log entries near it. Is there anything that will help me get more information about the culprit without pulling everything out and doing elimination diagnoses?

Office 2010 with current patches. Win7-64 with current patches.

Outlook is running all the time, I suppose? It sounds indeed like one of the 3rd-party Outlook add-ons being the culprit. There is no other way than to disable e.g. half of them, and wait for the error to happen again or not, and depending on the result either disable half of the enabled ones, or disable this half and enable the other half. At least that is the way you can troubleshoot if there are lot of add-ons.
If there are only a few, say 4, and/or you can tell which add-ons will perform actions on receive/delete/whatever (instead of being triggered manually), it's better to switch off either the most suspect one(s) - getting positive response as "no error occurs within a certain time span", or switch on only those - getting negative response as "error occurs".

Thanks for the post, but what you describe is what I said I was trying to avoid.

"There is no other way" - unless the faulty add-on creates a log file somewhere.

I've requested that this question be deleted for the following reason:

Only 1 responder. Responder gave steps to do what I said I was trying to avoid. When I reiterated that, he said that was the only way. Don't know how to award any points for a "there is no answer" answer.
