Answer 2

It is a Windows error, facility code 7. The last word gives the Windows error, 0x6be == 1726:

// MessageId: RPC_S_CALL_FAILED
//
// MessageText:
//
// The remote procedure call failed.
//
#define RPC_S_CALL_FAILED                1726L

Interop with Office programs like Outlook happens through out-of-process COM. RPC is the low-level Remote Procedure Call mechanism. There are several reasons for such a remote call to fail. Both the error code and the error name google well.

The simplest explanation is just that Outlook fell over. That happens. The advantage of in-process interop is that when the host program crashes then it will take out your code as well. Not in an out-of-process scenario, you just get a hard to diagnose error. Ask your customer's IT staff to use their typical Office troubleshooting strategies.
