Hi,

I has anybody encountered the following behaviour:
COM exception thrown from Outlook, when handled in .Net,
has different HRESULT every time, for the same error..

E.g.
I cause an exception by using a wrong filter in restrict (adding ZZZ)


Outlook.Items inboxItemsCollection;
inboxItemsCollection.Restrict("[ReceivedTimeZZZ = '#2/23/2006
14:18#'")

I get exception:
"The property "ReceivedTimeZZZ" is unknown."

The value in class System.Runtime.InteropServices.COMException
of ErrorCode is -1317928951

and in another call it will be
ErrorCode -1005453303

on every call (exception), ErrorCode will get a different value.


Is this a known problem ? in Outlook ? Interop ?
It occurs on various methods, not just Restrict.

It is also discussed he

Thanks for any help.
