Error occurs very intermittently (can't be reproduced) when users click the send button. My code appears to be running in the Inspector_Activate event when the item disappears.
Here's a stack trace from the exception:

---- Stack Trace ----
It's my understanding that the original edited item is destroyed in the process of committing and sending new emails. However, I don't understand how to safeguard against errors this might cause. Am I on the right track, and if so then what should I be doing?
EDIT:
Another developer came to me with a similar "Object reference not set to an instance of an object" error -- this time it was in the Explorer SelectionChange event, and the innermost error said "The Explorer has been closed and cannot be used for further operations. Review your code and restart Outlook."
Am I doing something wrong here??? |

UPDATE:
Okay, the way I see it, I'm dealing with navigation events where perhaps I'm making some incorrect assumptions. For example, if it's possible for there to be an Explorer SelectionChange event where there is no current folder, or an InspectorActivate event where there is no current item or commandbar, then those situations could cause these exceptions.
Are there any guidelines for this??? |
