System.Runtime.InteropServices.COMException (0x800706BE) when getting contact.LastName

Question

Some of our users are getting this exception sometimes (not for every contact):

System.Runtime.InteropServices.COMException (0x800706BE): 
   The remote procedure call failed. (Exception from HRESULT: 0x800706BE)
   at Microsoft.Office.Interop.Outlook._ContactItem.get_LastName()

This happens when we're trying to get the last name of a contact (of the ContactItem type).

Does anybody know what the problem is?

Any help would be appreciated. Thanks!

Hi Andrei can you post some code. – Pseudohermaphrodite

Answer 1

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.

If you got here because of Excel Interop it is probably because of "FoxitReader PDF Creator COM Plugin" see : https://mcmap.net/q/2031108/-excel-interop-workbooks-open-inconsistencies – Gamopetalous

Answer 2

set the full access to Network Services (or identity of apppool) to the folder C:\Windows\System32\config\systemprofile\AppData
