VSTO: COM Exception 0x800A01A8
Posted by Tim Valentine in VSTO on August 20, 2011
Problem
COM exceptions that give you just a HRESULT to describe an exception are terrible. During some VSTO development for Outlook 2007, I kept getting a COM exception with an HRESULT of 0x800A01A8, and eventually I found the reason why I was receiving the exception. I though I’d share since little information is available on this particular exception.
