Hello @Derek Teague,
HRESULT 0x80040401 appears to be a MAPI_Timeout error. In other words, the VBO is trying to access the message store and for some reason it's being delayed and the request times out.
When this occurs, does the particular mailbox have a lot of mail in it?
This thread discusses one possible solution:
