Readers, if you're here because you need help, please DO NOT start by following the suggestions in the article.  

The article posted here is thin on details and isn't really a fix for anything.  They're general steps which could be applied to ANY problem.  Scan and edit your registry (but "only if you're an expert") is the first step of the article's suggestion.  How about backing up the registry first in case you really bugger things up?    Maybe you have a virus.   Ok, so far that's 2 suggestions that are extremely general.  Next, clean up your junk mail folder.  Sure, you're getting the error because you have too much mail or something.  Why wouldn't this be step one?  We know that won't do anything, so then just uninstall and reinstall Office.  That's a pretty big step.  Next try windows updates.  More general tasks.  Why wouldn't updating windows be before reinstalling office?   And the last step, the author doesn't have any real fixes so she suggests simply wiping your system and starting from scratch.
