Question : Name within brackets showing up when typing in senders text on an email.

Sorry that the title is so confusing.  Here is the scenario.  I have a user that is having a problem while using Microsoft Outlook.  When she tries to compose a reply and she types anywhere within the body of the e-mail that was written by the sender, this shows up [J DOE].  They do this sometimes to answer questions right below that question.  It seems harmless enough.  I even considered that it is intentional so that in the paper trail of the e-mail, you can know what was written by whom.  The problem is that it isn't her name that shows up.  Does anybody know what this is and how to stop it from happening?  I have tried recreating her mail profile.  That didn't work.  This server is running Server 2003 R2 and Microsoft Office Pro 2003.  Any and all help would be greatly appreciated.  If you have any questions, ask away.  Thanks again for reading.

Answer : Name within brackets showing up when typing in senders text on an email.

What this is a sign of is people POSTing large chunks of data to your website.  These are not compilation files, but instead contain a cache of the POST data sent to your website:

Elsewhere on the web, I have read - ASP.NET 2.0 caches large POSTs to disk when the POST is
greater than 256 bytes by default. The default location for the cached
data on my machine is following:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET
Files\<appName>\<tempFolder>\<tempFolder>\uploads

Not knowing how your app is written, or what it accepts, I could not tell you if a large POST cache is a sign of hacking or if it's part of normal operation - you'd have to examine your application and what expected POST data you're getting (file uploads? - post-cache substitution? session-state out of control?)
