Dmitry,
Thanks for your response. I don't think that I can safely ignore
the exception because it is failing to move the email. I ran the code
in the debugger and got some more detail on the exception:
Exception: System.Runtime.InteropServices.COMException (0xC6220009):
Can't move the items.
ErrorCode = -970850295
HelpLink =
InnerException =
Message = Can't move the items.
Source = Microsoft Outlook
TargetSite = System.Object
Move(Microsoft.Office.Interop.Outlook.MAPIFolder)
I did a search on MSDN and Usenet but couldn't find anything for the
HRESULT = -970850295. Is there some source that lists all possible
Outlook ErrorCodes/HRESULTs?
I think that the .NET equivalent of IDispatch.Invoke() would be to use
the classes of the System.Reflection namespace, but I am not sure how
this would help me here. It seems like I am able to programmatically
move EmailItems to different folders, but as soon as I open/move them
in the GUI, the code stops working. Is there anyway to see if some
other process/thread has locked the item? Is there some other API
that I should/could be using (e.g. MAPI vs. OOM)?
Thanks,
Jim Capenter
