Hi,

I'm developing an e-mail archiving solution which archives Outlook Express and Windows Mail.

Some customers report that while processing some of their e-mail messages, errors are thrown. The errors occur when I call IStoreFolder:penMessage (IStream) -- I'm not able to reproduce them, and many customers don't have them.

• COM-Exception 0x800C006C (very frequent)
  
• SystemAccessViolationException (rare)
  

Can someone tell me what this 0x800C006C error means? Or what can cause both errors?
Unfortunately, 0x800C006C is not listed anywhere.

Thanks very much in advance,
Stefan Schultze
